This four-disc, 68-track collection paints a broad definition of the blues, with cuts ranging from vintage country blues (Robert Johnson's “Cross Road Blues,” Son House's “Death Letter Blues”) to uptown jazz blues (Nina Simone's “Blues for My Mama,” Billie Holiday's “Billie’s Blues”), Chicago blues (a live version of “Howling Wolf” by Muddy Waters), British blues (Jeff Beck's “JB’s Blues”), and contemporary acoustic blues (“Am I Wrong” by Keb' Mo'), with plenty of stops in between, making for a random but varied playlist that circles the different approaches and musical definitions of the genre.

So Many Roads is Hammond's most notable mid-'60s Vanguard album, due not so much to Hammond's own singing and playing (though he's up to the task) as the yet-to-be-famous backing musicians. Three future members of the Band – Robbie Robertson, Garth Hudson, and Levon Helm – are among the supporting cast, along with Charlie Musselwhite on harmonica, and Mike Bloomfield also contributes. It's one of the first fully realized blues-rock albums, although it's not in the same league as the best efforts of the era by the likes of the Paul Butterfield Blues Band or John Mayall's Bluesbreakers. In part that's because the repertoire is so heavy on familiar Chicago blues classics by the likes of Willie Dixon, Bo Diddley, and Muddy Waters; in part that's because the interpretations are so reverent and close to the originals in arrangement; and in part it's also because Hammond's blues vocals were only okay.

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.

Friends is the accurate and revealing title for New York bluesman Eric Bibb's tenth album since 1997. There are 15 cuts here, each of them featuring rootsy folk and blues collaborations with different "friends" in differing small group settings. The set starts with a killer acoustic slide duet between Bibb and Guy Davis on the nugget "99 ½ Won't Do." The contrast between Davis' sweet and smoky delivery and Bibb's husky wail – akin to Blind Willie Johnson's in places – offers a double-sided dimension in interpretation for the listener, as well. Elsewhere, Charlie Musselwhite gives a killer snaky harmonica performance on "Six O' Clock Blues." Taj Mahal makes two appearances; one in a duet on "Goin' Down Slow," and one in a trio with Bibb and Malian guitarist Djelimady Tounkara on a medley of the traditional "Kulanjan" and Bibb's own "Sebastian's Tune."

This recording has a less-than-stellar reputation, principally because it was done so late in McTell's career, and it is true that he lacks some of the edge, especially in his singing, that he showed on his other postwar recordings. On the other hand, his 12-string playing is about as nimble as ever and a real treat. McTell cut these sides for record store owner Ed Rhodes, who had begun taping local bluesmen at his shop in Atlanta in the hope of releasing some of it – McTell took to the idea of recording only slowly, then turned up one night and played for the microphone and anyone who happened to be listening, finishing a pint of bourbon in the process – the result was a pricelessly intimate document, some of the words slurred here and there, but brilliantly expressive and stunningly played.

This record was originally released in 1991 after Taj had taken a break for a number of side projects including children's records. He was obviously refreshed - the record is full of new ideas and incorporates new production techniques, check out the lovely song "Every wind in the river" and also the scratching and rap stylings of "Squat that rabbit". A bit radical for blues but both work very well. Taj revists the song "Giant step" and also takes the traditional blues "Blues with a feeling" to New Orleans, with an added dash of steel guitar (!?!). Guests include banjo player David Johnson, guitarist David Lindley, Andy Kravitz and Bill Summers and the backing band sound great throughout. This is a really good, imaginative record that saw Taj coming back to form and his next couple of records in the 90s were even better.

Señor Blues is one of Taj Mahal's best latter-day albums, a rollicking journey through classic blues styles performed with contemporary energy and flair. There's everything from country-blues to jazzy uptown blues on Señor Blues, and Taj hits all of areas in between, including R&B and soul. Stylistically, it's similar to most of his albums, but he's rarely been as effortlessly fun and infectious as he is here.

From the opening bars of Soul on Fire you could be forgiven for thinking you were listening to a new Ry Cooder album at last but you would be wrong by a windmill or two. Influenced by the likes of Leadbelly and Big Bill Broonzy, Dutch guitarist Hans Theessink (pronounced "tay-sink") successfully moves across musical borders with ease on his 15th album. Lifeline is just the right mixture of deftly played acoustic blues, gospel and soul channelled into a union that highlights the diversity and durability of roots music at it's best with guests like Charles Brown and The Holmes Brothers. There are 11 excellent original tracks to soak up, as well as covers of Rev Gary Davis, Blind Willie Johnson, and the Neville Brothers. A rare treat!

Time traveler Alvin Youngblood Hart's albums have darted from crusty Delta fingerpicking and hollering to Hendrixian hellfire to crunchy, primal rockin' blues, all with the ring of authority that comes from complete commitment to the music. This time, he's set the wayback machine to the early '30s, using guitars, mandolin, banjo, and a lot of heart to interpret tunes by Son House, Charley Patton, Skip James, Leadbelly, and others. Somehow, the dust of old Mississippi, the state where the Oakland-born musician now resides, seems to have gotten into his blood. Hart sounds like Parchman Farm's newest inmate as he wails and moans through "How Long Before I Can Change My Clothes," plucking notes from a National resonator guitar. Chiming out chords and quick runs on banjo, he makes Odetta's "Chilly Winds" seem like they're carrying the voices of lost ghosts, recounting their lives of misery under Jim Crow's wing. Hart tends to take many of these classics, like Patton's "Tom Rushen Blues" and Leadbelly's "Alberta," at slightly slower tempos, which gives him more time to squeeze gut emotions from his lightly graveled phrases and lets his pluck-and-drone playing work its hypnotic effect. Stark and impressive for the power Hart generates alone, this may be the acoustic blues album of the year.

Just as the title says: a wonderful brace of simple country blues done in Jackson's warm Piedmont style. At age 75, his fingers are still nimble as he displays on a jazzy "Just Because" and his vocals still resonate nicely. Audiophile note: This album is nicely recorded and sounds like Jackson is performing about two inches from your face. A warm and engaging batch of performances not to be missed.

The state of Mississippi is the undisputed home of the blues - the single most important source of modern popular music. From the towering influence of Delta legends Charley Patton and Son House to the guitar intricacy of Skip James and Mississippi John Hurt, this collection highlights the remarkable blues legacy of the Magnolia State through these seminal early recordings.

Guy Davis continues to explore the almost forgotten territory of acoustic African-American folk music, field hollers, shouts, rags, and gospel songs in a style that predates the blues and has much in common with the white Appalachian music that existed until the record companies separated it into race and hillbilly music. "Slow Motion Daddy" is a salacious ragtime original with a syncopated rhythm that recalls Rev. Gary Davis and Willie McTell. Davis plays banjo and harmonica and hams it up giving the performance a sly humor. "Follow Me Down" is a 12-string guitar showcase that pays homage to Leadbelly's "Mr. Tom Hughes' Town" a tale of racism and high life in the big city. Nerak Patterson adds electric guitar to a cover of "Hoochie Coochie Man" in an arrangement that crosses the Delta with South Side Chi town. Davis delivers the tune with a growling sexuality and leaves Patterson room for a tasty solo. "Can't Be Satisfied" is another Muddy Waters' tune, this time played claw hammer style on the banjo, with Davis adding harmonica and delivering another playful vocal.
