Blues With a Message isn't just about lost love and the toils of specific lives, the blues (particularly within the folk-blues traditions) spent some time dealing with sociopolitical issues on the side, primarily before the rise of electric blues. Here, Arhoolie has compiled a set of pieces related to a surprisingly large number of issues. Among them: Minstrel shows, the mechanization of cotton farming, and its related exodus to the North, sharecropping, segregation, the Korean War, the influenza epidemic, the New Deal, civil rights movements, Chicago employment opportunities – all are given a song or two here. The music quality is roughly equivalent to many of the folk-blues recordings available, though the "big name" artists are largely absent from this one (Lightnin Hopkins does make an appearance singing about sharecropping, however). The songs are deliberately focused on the issues more than the music, but the music can still carry its soul. This one probably won't be on many highest-sales lists in the blues, but it's both historically important and musically enjoyable.

The sounds of New Orleans have always been in Maria Muldaur's blood and catalog. Dr. John appeared on her first solo album back in 1974 and she arguably hit a career high point on her first full-fledged love letter to the city, 1992's Louisiana Love Call. She returns to the Crescent City for this 2011 release, employing veteran New Orleans keyboardist Dave Torkanowsky as musical director and "facilitator" and returning to the swampy "Bluesiana music" sound that includes heavy doses of gospel and blues along with touches of jazz, soul, and funk. This is a major shift from her past two acoustic jug band releases and plays to her sultry strengths as a vocalist who can convincingly sing any style of music she feels passionate about. Muldaur revisits a few tracks she has previously recorded (an earlier version of "As an Eagle Stirreth in Her Nest" was included on 1976's Sweet Harmony) but with a band that features guitarist Shane Theriot and Subdudes bassist Johnny Allen, they and the rest of the handpicked material boil with fresh enthusiasm.

Any time two greats who admire each other and are musically compatible team together, the results are usually mutually beneficial. That was true for Bill Monroe and Doc Watson, whose spirited union on this 17-song disc is a sampler of American musical styles. They ripped through bluegrass, folk, blues, spirituals, mountain tunes, work songs, reels and breakdowns. Monroe's mandolin and Watson's guitar playing were masterful, wondrous and performed without any trace of self-indulgence. Their vocals were also delivered with ease, fluidity and conviction, the product of two performers completely at ease with themselves and only interested in spotlighting the material.

While Johnny Cash at Folsom Prison, the 1968 album that made Cash a household word, spent only two weeks at No. 1, this 1969 follow-up topped the charts for 20 weeks. As with Folsom, the San Quentin LP had to be edited due to space limitations. Now, 31 years after the fact, the show can at last be heard in true perspective. All the original performances hold up, including the album's hit single: Shel Silverstein's "A Boy Named Sue," presented unbleeped for the first time. Equally impressive are the eight restored tracks and unexpurgated between-song patter. Cash's opening renditions of "Big River" and "I Still Miss Someone" are bracing. So are four closing songs teaming Cash with his complete performing troupe (the Carter Family, Carl Perkins, and the Statler Brothers). Their gospel performances ("He Turned the Water into Wine," "The Old Account," and an early version of "Daddy Sang Bass") are electrifying, as is a concluding medley featuring everyone. Cash is presented here at his roaring, primal best.

A great album and the release that made Roberta Flack a major soul and R&B artist in the early '70s. She had a soft, compelling, alluring voice, and was able to convincingly switch gears and also convey anger, regret, hurt, or despair. Those who thought Flack was a one-hit wonder, or didn't think she could make the transition from doing mostly jazz to other styles, were convinced otherwise.

The unmistakable voice of Whitney Houston is powerful and timeless. She is one of the best-selling artists of all time with sales of over 200 million records worldwide and is the only artist to have had seven consecutive number-one singles on the Billboard Hot 100. She reached the pinnacle of pop success, becoming one of the most accomplished recording artists of all time. But her heart was always in Gospel music, and it profoundly influenced her life and career. I Go To The Rock captures her Gospel music journey. Featuring six never-before-released songs, the album gives a glimpse of the deep faith behind the voice that continues to uplift and impact countless lives around the world.

The second full-length from sacred steel genius Robert Randolph & the Family Band delivers, from the studio, the same promise, grit, grease, and sweat that Live at the Wetlands did. Randolph pulls out the stops in the studio, using his own band, without any of the hotshot guest stars who he's appeared with in the last two years. Unclassified features a road-tested, studio-savvy band using all of its collected gifts with producer Jim Scott to make a record that is as much about soul, funk, hard rock, folk, and jam band intensity as it is about the gospel music that first inspired the unit.
