With 1970's Workingman's Dead, the Grateful Dead went through an overnight metamorphosis, turning abruptly from tripped-out free-form rock toward sublime acoustic folk and Americana. Taking notes on vocal harmonies from friends Crosby, Stills, Nash & Young, the Dead used the softer statements of their fourth studio album as a subtle but moving reflection on the turmoil, heaviness, and hope America's youth was facing as the idealistic '60s ended. American Beauty was recorded just a few months after its predecessor, both expanding and improving on the bluegrass, folk, and psychedelic country explorations of Workingman's Dead with some of the band's most brilliant compositions. The songs here have a noticeably more relaxed and joyous feel.

Like 1999's tribute to Gram Parsons, Return of the Grievous Angel, this successful collection revives the tired "tribute" concept and applies it in homage to a key figure in country music. Interpreting songs from across Hank Williams's short and troubled career, a range of high-profile artists use different approaches with equally gratifying results. Tom Petty, Sheryl Crow, and Hank Williams III play familiar songs with traditional arrangements (Ms. Crow's yodel is an eye opener); Beck, Mark Knopfler, and Keb' Mo' stay closer to their own idioms. Keith Richards's reedy vocal makes "You Win Again" all his own, and Bob Dylan, who has only rarely lent his services to these sorts of projects, leads his touring band through a blues shuffle on "I Can't Get You Off of My Mind." The estimable Lost Highway label has assembled an illustrious cast to sing the praises of the artist who inspired its name, and in doing so it has created a far better testament to its musical mindset than can ever be captured in the term Americana.

Townes Van Zandt was a one-of-a-kind artist who blazed a new trail for singer/songwriters, conjuring a sound that combined elements of country and folk with his own artful melodic sensibility, matched with lyrics that were personal, poetic, and impressionistic while remaining firmly down to earth. A new breed of Texas singer/songwriters followed Van Zandt's example, and it's all but impossible to imagine artists like Guy Clark, Jimmie Dale Gilmore, or Steve Earle finding their voice without his guiding influence. This two-disc set features Van Zandt's first two albums, 1968's For the Sake of the Song and 1969's Our Mother the Mountain.

This one-man extravaganza finds John Fogerty plowing the same ground he worked with Creedence Clearwater Revival. This mix of originals and rock & roll classics finds him in fine voice, with the familiar vocal scream and hot guitars augmented in places by saxophones reminiscent of CCR's "Travelin' Band." Several of these songs rank with the top tier of Fogerty's Creedence material, particularly "The Wall," "Almost Saturday Night," and the anthemic "Rockin' All Over the World." He also delivers satisfying versions of Jackie Wilson's "Lonely Teardrops" and Frankie Ford's "Sea Cruise" (written by Huey "Piano" Smith). The closer, "Flyin' Away," could have come off the Doobie Brothers' Toulouse Street. This underappreciated album is worth checking out.

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.

Released in 1992, Hollywood Town Hall wasn't a hit, but it received enough rave reviews to considerably raise the Jayhawks' profile, and it certainly heightened expectations for their next album. On 1995's Tomorrow the Green Grass, the Jayhawks found themselves in the tricky situation of trying to match the quality of Hollywood Town Hall without simply repeating themselves, and they came remarkably close to achieving that daunting task.

This CD opens with an outrageous and exceedingly funky "UFO Has Landed in the Ghetto," and which seems so out of place with the other material. Yes, it is a rhythm & blues, bordering at times on funk album, and rap is one direction R&B took, but…. Listen to the groove on "Which Came First," and try to keep your body from bobbing to the strong rhythm laid down by Jim Keltner, Tim Drummond, and the background vocalists. While we are on the subject of vocals, this is one of Ry Cooder's best efforts, and his backup vocalists are key here and deserve special recognition: Bobby King, John Hiatt, Willie Greene, and Herman Johnson for most of the CD. The two gems on this are the phenomenal treatments of both "Blue Suede Shoes" and Bob Dylan's "I Need a Woman." Two songs as different in the original forms as pigs and gerbils are converted to R&B hit status. Both contain some memorable slide guitar work, but isn't that what we expect from this master of the guitar family. The album is very good but those two songs make it a gem.

On this, Charlie Daniels' second release, there are obvious signs of a bright future for the guitar- and fiddle-playing hillbilly rocker. Along for the ride is Joel "Taz" DiGregoria, Charlie's longtime bandmate and keyboard wizard. Taz even takes lead vocal duties on one song, "Billy Joe Young," and his ivory tickling is a highlight of this historical Southern rock document. Daniels rocks with the intensity of a downbound train on "Great Big Bunches of Love," and on his cover of the Jerry Lee Lewis chestnut "Drinkin' Wine, Spo-Dee-O-Dee." A true Southern poet, Charlie Daniels is seen here in the infancy of his artistic development, but even at this early stage, the poet is alive and well.
