Among musicians, Arthur Alexander was always considered one of the greatest R&B songwriters. Both the Beatles and the Rolling Stones covered his songs, "Anna (Go to Him)" and "You Better Move On," respectively, early in their careers. But they weren't the only ones – throughout the years, his work was rich source material for many blues, soul, rock, and country artists. He may have earned the recognition of his peers, but he remained relatively unknown to the general public, right up to his death in 1993. In order to raise his profile, Razor & Tie released Adios Amigo: A Tribute to Arthur Alexander in 1994, assembling a stellar and diverse lineup to record new versions of his songs. The diversity and the fresh arrangements illustrates the depth of Alexander's songs and how well they lent themselves to new readings. Like any tribute album, Adios Amigo is uneven, with a few tracks falling flat, but the best moments – Elvis Costello's "Sally Sue Brown," Robert Plant's "If It's Really Got to Be This Way," Chuck Jackson's "You Better Move On," Frank Black's "Old John Amos," John Prine's "Lonely Just Like Me," Gary U.S. Bonds' "Genie in the Jug," Graham Parker's "Every Day I Have to Cry" and Nick Lowe's "In the Middle of It All" – are affectionate salutes to a departed master, and they're damn enjoyable in their own right as well.

For years, Led Zeppelin fans complained that there was one missing item in the group's catalog: a good live album. It's not that there weren't live albums to be had. The Song Remains the Same, of course, was a soundtrack of a live performance, but it was a choppy, uneven performance, lacking the majesty of the group at its peak. BBC Sessions was an excellent, comprehensive double-disc set of their live radio sessions, necessary for any Zeppelin collection (particularly because it contained three songs, all covers, never recorded anywhere else), but some carped that the music suffered from not being taped in front of a large audience, which is how they built their legacy - or, in the parlance of this triple-disc collection of previously unreleased live recordings compiled by Jimmy Page, How the West Was Won. The West in this case is the West Coast of California, since this contains selections from two 1972 concerts in Los Angeles…

For all of the acclaim it received, there's no denying that No Quarter was a tentative reunion for Page & Plant, containing only a handful of new songs that were scattered among many reworked old favorites. Since its supporting tour went well, the duo decided to make their reunion permanent, setting to work on an album of entirely new material. Taking the world music dabblings of No Quarter as a cue, Page & Plant tempered their eclecticism with a healthy dose of their monolithic guitar army, hiring Steve Albini, the indie rock producer notorious for his harsh, brutal recordings, to helm the boards. In other words, it sounds perfect on paper - groundbreaking veteran artists still taking chances and working with younger collaborators who would challenge them…

Jimmy Rogers was very much a musician's musician – the kind of guitarist that earned accolades from contemporaries and successors alike – yet one who never wins a wide, mainstream audience. Blues Blues Blues was designed as the album that would find Rogers a larger audience, and as such, it has all the bells and whistles of a big-deal blues album. It has the classics ("Trouble No More," "Bright Lights, Big City," "Sweet Home Chicago," "Don't Start Me to Talkin'"), remakes of Rogers standards ("Ludella," "That's All Right"), cult covers (Muddy Waters' "Blow Wind Blow," which kicks off the album on just the right note) and an astounding number of guest appearances, including cameos from (get ready): Jimmy Page and Robert Plant, Keith Richards and Mick Jagger, Lowell Fulson, Johnnie Johnson, Eric Clapton, Taj Mahal, Ted Harvey, Carey Bell, Stephen Stills, and Jeff Healey.

Robert Plant opens Carry Fire with "The May Queen," a song that can't help but stir up memories of "Stairway to Heaven," the most mystical number Led Zeppelin ever cut. "The May Queen" doesn't sound a thing like "Stairway to Heaven," which is deliberate. As Plant murmurs about "the dimming of his light," the churning folk-rock – a rootless, restless gypsy hybrid of American, English, and Middle East traditions – comes to crest upon a violin line that appears to quote "Prodigal Son," a gospel blues attributed to Robert Wilkins. It's hard not to read this as a sly wink to the audience, a suggestion that Plant, after years of rambling, has returned to where he belongs.

At their best, cover albums have a strange way of galvanizing an artist by returning to the songs that inspired them; the artists can find the reason why they made music in the first place, perhaps finding a new reason to make music. Robert Plant's Dreamland – his first solo album in nearly ten years and one of the best records he's ever done, either as a solo artist or as a member of Led Zeppelin – fulfills that simple definition of a covers album and goes beyond it, finding Plant sounding reinvigorated and as restless as a new artist. Part of the reason why this album works so well is that he has a new band – not a group of supporting musicians, but a real band whose members can challenge him because they tap into the same eerie, post-folk mysticism that fueled Led Zeppelin III, among other haunting moments in the Zep catalog.

After years of trying to separate himself from his legendary status as Led Zeppelin's frontman, Robert Plant finally reconciles with his past on Now & Zen. He borrows a few Zeppelin riffs, and even enlists Jimmy Page to play guitar on his hit "Tall Cool One." This album is also notable in that it marks his first collaboration with keyboardist Phil Johnstone, who would continue to play and write with Plant on subsequent albums. Musically, the album relies on standard rock arrangements except that the vocals and drums are at the forefront and keyboards instead of guitars are used to fill out the sound. Although most of the album is comprised of mid-tempo songs aimed at rock radio, Plant includes the lovely ballad "Ship of Fools," which demonstrates that he is more than capable of vocal subtlety…

In 2007, Robert Plant & Alison Krauss released Raising Sand, one of the most acclaimed albums of the 21st Century. It was an unlikely, mesmerizing pairing of one of rock’s greatest frontmen with one of country music’s finest and most honored artists, produced by the legendary T Bone Burnett. Now, after 14 years, they return with Raise the Roof, a dozen songs from a range of traditions and styles that extend this remarkable collaboration in new and thrilling directions.

Robert Anthony Plant CBE (born 20 August 1948) is a British singer and songwriter, best known as the lead singer and lyricist of the English rock band Led Zeppelin…

As the lead singer of Led Zeppelin, Robert Plant seemed invincible, a "Golden God" in the words of journalist/filmmaker Cameron Crowe. Plant may have embraced rock stardom at the height of Zeppelin's zenith in the mid-'70s, but the singer spent the decades following the band's 1980 dissolution exploring the road less-traveled.
