When Willie Dixon left his native Mississippi and traveled north to Chicago, he almost single-handedly dragged the blues with him into the modern era, giving the country blues a hard, new sheen with his deft songwriting, sturdy bass playing, and his considerable talents as a producer and arranger. This two-disc, 47-track set catches Dixon wearing all of his hats, with the first disc featuring him in the studio and in concert (including several live tracks with Johnny Winter) and the second spotlighting his bass playing and production work with the likes of Robert Nighthawk, Eddie Boyd, Muddy Waters, Little Walter, Lowell Fulson, Bo Diddley, Willie Mabon, and Howlin' Wolf. What emerges is a well-rounded portrait and introduction to one of the major architects of the modern blues sound.

As the Beatles' Sgt. Pepper's Lonely Hearts Club Band (1967) had done a year earlier, Super Session (1968) initially ushered in several new phases in rock & roll's concurrent transformation. In the space of months, the soundscape of rock shifted radically from short, danceable pop songs to comparatively longer works with more attention to technical and musical subtleties. Enter the unlikely all-star triumvirate of Al Kooper (piano/organ/ondioline/vocals/guitars), Mike Bloomfield (guitar), and Stephen Stills (guitar) – all of whom were concurrently "on hiatus" from their most recent engagements. Kooper had just split after masterminding the groundbreaking Child Is Father to the Man (1968) version of Blood, Sweat & Tears. Bloomfield was fresh from a stint with the likewise brass-driven Electric Flag, while Stills was late of Buffalo Springfield and still a few weeks away from a full-time commitment to David Crosby and Graham Nash. Although the trio never actually performed together, the long-player was notable for idiosyncratically featuring one side led by the team of Kooper/Bloomfield and the other by Kooper/Stills.

Otis Rush and Buddy Guy were hot young Chicago guitar slingers in the 1950s, when legends like Muddy Waters and Howlin' Wolf ruled the Second City. Rush was renowned for his nasty, over-amplified guitar sound, and songs like "All Your Love" and "Double Trouble" were seminal touchstones for such `60s British guitarists as Eric Clapton and Peter Green. Rush has lately been known more for live shows than records, and 1994's Ain't Enough Comin' In succeeded because it was programmed like a great concert set, with fat guitar solos that suggested Albert King in a sweat, and songs that drew from both the blues and soul songbooks. Rush sounds great singing Sam Cooke's good-news gospel ("Somebody Have Mercy" and "Ain't That Good News") and pays his propers to Ray Charles on "A Fool for You." Exciting takes on epic tunes associated with B.B. King ("It's My Own Fault") and Albert King ("As the Years Go Passing By") also leave no doubt that Rush hasn't forgotten how to burn down the house.

Chester Arthur Burnett, known as Howlin' Wolf, was a Chicago blues singer, guitarist and harmonica player, originally from Mississippi. With a booming voice and looming physical presence, he is one of the best-known Chicago blues artists. Musician and critic Cub Koda noted, "no one could match Howlin' Wolf for the singular ability to rock the house down to the foundation while simultaneously scaring its patrons out of its wits." Producer Sam Phillips recalled, "When I heard Howlin' Wolf, I said, 'This is for me. This is where the soul of man never dies'". Several of his songs, including "Smokestack Lightnin'", "Back Door Man", "Killing Floor" and "Spoonful", have become blues and blues rock standards. In 2004, Rolling Stone magazine ranked him number 51 on its list of the "100 Greatest Artists of All Time."

On Buddy Guy's second Silvertone release, he continues the practice of guest appearances begun on Damn Right, I've Got the Blues. In this case, the notables include Paul Rodgers, Travis Tritt, and John Mayall. The finest combination comes when Bonnie Raitt joins Guy on John Hiatt's "Feels Like Rain." Raitt's gritty vocals and sweet slide guitar add a pleasing nuance to the bittersweet track, and it is ultimately the high point of the record. Certain critics and blues purists have derided Guy's search for mainstream success as evidenced by his penchant for guest appearances and non-traditional blues forms, but Guy sounds fantastic in these unconventional situations (witness his burning version of the Moody Blues' "I Go Crazy").

Although Albert King is pictured on the front cover and has the lion's share of tracks on this excellent compilation, six of the fourteen tracks come from Rush's shortlived tenure with the label and are some of his very best. Chronologically, these are his next recordings after the Cobra sides and they carry a lot of the emotional wallop of those tracks, albeit with much loftier production values with much of it recorded in early stereo. Oddly enough, some of the material ("All Your Love," "I'm Satisfied [Keep on Loving Me Baby]") were remakes – albeit great ones – of tunes that Cobra had already released as singles! But Rush's performance of "So Many Roads" (featuring one of the greatest slow blues guitar solos of all time) should not be missed at any cost.

The Live Adventures of Mike Bloomfield and Al Kooper is a double album recorded at the Fillmore West venue; the album is a successor to the studio album Super Session, which included both Bloomfield and Kooper in addition to Stephen Stills, and had achieved commercial and critical success earlier in 1968. The performances, recordings and production cannot be described as flawless; in his sleeve notes, Kooper describes the difficulties of finding rehearsal space, Bloomfield's insomnia, and the failure of a vocal microphone during "Dear Mr Fantasy"; the track "I Wonder Who" is faded during a Bloomfield solo for no apparent reason. Nevertheless, the album remains an important, if raw, document of a live blues-rock performance of the period and, apart from its intrinsic qualities, is notable not only for one of the earliest live recordings by Carlos Santana but also for Bloomfield's debut as a vocalist. Whilst he is not historically noted in this role, in "Don't Throw Your Love on Me So Strong", according to Kooper, "he displays consummate homage to the traditional guitar-voice trade-offs; a lesson in phrasing and understanding."

The title is a bit of a ringer, since this isn't a collaborative effort in any way, shape, or form. Muddy & the Wolf contains a half-dozen live Muddy Waters tracks with backing from Mike Bloomfield, Paul Butterfield, and Otis Spann, the material culled from the Fathers & Sons sessions. The set also features tracks by Howlin' Wolf from his London sessions with Eric Clapton and Ringo Starr. File under "just OK."

For the most part, another easy-going trip to the mellower side of contemporary blues, Robinson's jazzy tone and buttery vocals applied to a couple of his '50s-era numbers ("Crazy Crazy Lovin'" and "Schoolboy") along with some intriguing new iteams and Lowell Fulson's mournful "Sinner's Prayer." Tasty backing helps too. His Japanese fans reverently dubbed Fenton Robinson "the mellow blues genius" because of his ultra-smooth vocals and jazz-inflected guitar work. But beneath the obvious subtlety resides a spark of constant regeneration – Robinson tirelessly strives to invent something fresh and vital whenever he's near a bandstand.

This solid 2-disc compilation celebrates two decades of this label's existence. There are many worthwhile tracks but few surprises.

Starting with its 20th anniversary in 1991, every five years brings another double Alligator collection, and 2011 was no exception. While the 35th edition –released in 2006 – logically featured 35 songs, the compilers couldn't quite squeeze 40 onto this 40th anniversary disc, even though owner Bruce Iglauer does admit to fading a few endings off prematurely in order to maximize the list, which hits 38 selections. The trick with these albums is to both pay tribute to the label's storied past while including enough recent acts to connect the dots between the house-rocking music Iglauer built his company on, and the more modern yet still roots-based sounds he's released during the last five years.

By any yardstick, Chicago guitarist John Primer has paid his dues. Prior to making The Real Deal for Mike Vernon's Atlantic-distributed Code Blue label, Primer spent 13 years as the ever-reliable rhythm guitarist with Magic Slim & the Teardrops. Before that, he filled the same role behind Chicago immortals Muddy Waters and Willie Dixon. All that grounding has paid off handsomely for Primer. His sound is rooted in the classic Windy City blues sound of decades past: rough-edged and uncompromising and satisfying in the extreme. He's one of the last real traditionalists in town. By the time he came to Chicago in 1963, Primer was thoroughly familiar with the lowdown sounds of Waters, Wolf, Jimmy Reed, B.B. and Albert King, and Elmore James.

This 45-song, two-disc collection is subtitled "two decades of killer fretwork", and never was a set so aptly described. Chess Records was the home to seemingly every hot guitar player in the Chicago area, and many of them make their appearance here. Besides the usual label guitar hotshots (Muddy Waters, Jimmy Rogers, Chuck Berry, Bo Diddley, Buddy Guy, Lowell Fulson, Earl Hooker, Otis Rush, Robert Nighthawk, Little Milton), space is given to sideman work from legends like Hubert Sumlin and Robert Jr. Lockwood and great one-offs by lesser-known artists like Jody Williams, Danny Overbea, Eddie Burns, Joe Hill Louis, Morris Pejoe, Lafayette Thomas and others. It seems as if everyone recorded for Chess at one time or another, also explaining the inclusion of tracks by John Lee Hooker, Albert King, Clarence "Gatemouth" Brown, Lonnie Brooks, Hound Dog Taylor and Elmore James. If electric blues guitar's your thing, then look no further than this fine two-disc compilation.

The very thing that made Luther Allison noteworthy became an albatross around his neck. Years after his initial run of records in the '70s, he was known for the same thing he was at the time – he was the only blues artist on Gordy, or any Motown affiliated label. This was true and novel, but many focused on the novelty, not the truth, ignoring Allison's status as a terrific torchbearer of raw Chicago blues. Some of material illustrates some contemporary influence – dig that funky groove and organ on "Raggedy and Dirty," or the rock-oriented slow burn of Mel London's "Cut You A-Loose" – but as his original title track illustrates, he can also deliver a torturous, impassioned slow grind. Still, this isn't an album about originality, it's a record how tradition can remain alive in a contemporary setting. Apart from the slightly cleaner production and the extended running time, this could have been released 15 years earlier, since its heart is in classic Chicago blues, particularly Chess. He draws on Willie Dixon via Howlin' Wolf for the first two tracks, dipping into Elmore James and B.B. King's catalogs later on in the record.

The Chess Box does not contain all the great music Muddy Waters made. His talent and legacy are too large to be captured in a mere three discs, even one that spans from 1947 to 1972. This means, of course, that his legendary plantation recordings with Alan Lomax are not here, nor is his dynamic late-'70s comeback, Hard Again. But, truth be told, it doesn't feel like they're missing, since Waters' legend was built on the music that he made for Chess, and much of the greatest of that is here. Few box sets have chronicled an artist's best work as effectively as this; even the handful of rare, previously unreleased recordings sit perfectly next to the essential singles (this is particularly true of alternate takes of Fathers and Sons material). Sure, there are great Chess sides that aren't here, but those are great sides that the serious listener and aficionado need to seek out. For everybody else, this is a monumental chronicle of Waters at his best, illustrating his influence while providing rich, endlessly fascinating music.
