One of the long-standing collaborations of the British folk revival, Bert Jansch and John Renbourn's Bert and John sees the masterful Pentangle guitarists sparing together through their trademark steel-string guitar styles. Their respective solo careers established them both as leading troubadours of British Isles folk, with little debate and few peers, besides maybe Wizz Jones and Ralph McTell. On this album the duo finds good company in each other's techniques, which are quite indistinguishable in both guitar playing and singing through traditional adaptations, blues, and originals in the Anglo-folk style. The duo plays beautifully together in a candid setting.

Why they kept these 19 recordings locked up in some vault for 40 years is beyond comprehension. A chunk of the Live at Sugar Hill material – recorded at a club in the Bay Area – was issued by Fantasy as Boogie Chillun on LP in 1972. It is available on CD minus one track under the same title. As good as that material was, these tracks from the very same gig are hands down some of the sexiest, deepest blues John Lee Hooker ever recorded – and that's saying something. Accompanied only by his hollow-bodied electric guitar and his foot on the floor, Hooker takes listeners through a performance so intimate that you wonder if there was an audience present – there is clapping, but not much. Versions of "Crawling King Snake," "Bottle Up and Go," "Let's Get It," "Jelly Jelly," "What's the Matter Baby," "You Don't Miss Your Water," "I Can't Hold On," and others get perhaps their definitive versions here. The opening track, "You Torture My Soul," is one of Hooker's most poignant moments, full of venom and vulnerability. In addition to the stellar performances, Hooker's guitar playing here is perhaps the finest of his career

John Hammond has dealt with issues of authenticity and origin, both musical and personal, and moved beyond them. This 18-song session, recorded live in 1983 and recently reissued on CD, may have been his definitive session. It was certainly a masterpiece, with Hammond doing confident, thoroughly distinctive versions of signature Delta and Chicago blues classics by Robert Johnson, Muddy Waters, Willie Dixon, Son House and others. While "Dust My Broom," "Drop Down Mama," "Wang Dang Doodle" and all the rest have certainly been done to death, Hammond's spirited vocals, riveting guitar work on acoustic or bottleneck and his overall charismatic performances made them seem like fresh discoveries.

Some find Karen Dalton's voice difficult to listen to, and despite the Billie Holiday comparisons, it is rougher going than Lady Day. But Dalton's vocals aren't that hard to take, and they are expressive; like Buffy Sainte-Marie, it just does take some getting used to because of their unconventional timbre. Her debut album has a muted folk-rock feel reminiscent of Fred Neil's arrangements in the mid-'60s, unsurprising since Neil's Capitol-era producer, Nick Venet, produced this disc too, and since Dalton, a friend of Neil, covered a couple of Neil songs here ("Little Bit of Rain," "Blues on the Ceiling"). Although clocking in at a mere ten songs, it covers a lot of ground, from Tim Hardin, Jelly Roll Morton, and Leadbelly to the traditional folk song "Ribbon Bow" and the Eddie Floyd/Booker T. Jones-penned soul tune "I Love You More Than Words Can Say." The record is interesting and well done, but would have been far more significant if it had come out five years or so earlier. By 1969 such singers were expected to write much of their own material (Dalton wrote none), and to embrace rock instrumentation less tentatively.

In 1959, John Lee Hooker signed a one-off deal with the Riverside label to record an acoustic session of the country blues. It was a key change from his earlier recordings, most of which had featured Hooker on an electric guitar with his trademark reverb and stomping foot. Folk purists of the day were delighted with COUNTRY BLUES, believing Hooker had returned to his roots, leaving the "glitzy commercialism" of R&B behind. But some Hooker fans considered COUNTRY BLUES a "betrayal" of his true sound.

From the sweet to the salacious to the poignant, Maria Muldaur's eponymous, strong debut features savvy studio vets, talented guests, strong tunes, and Muldaur's lissome pipes. The outstanding players include Ry Cooder, David Grisman, Clarence White, and Mac Rebennack, better known as Dr. John. A tasteful guitar solo by the underrated Amos Garrett elevates the charming surprise hit single "Midnight at the Oasis." Although she later gravitated to jazz and gospel, Muldaur's first outing is heavy on songs derived from country and blues. A rousing "Work Song," borrowed from Kate & Anna McGarrigle, is only one of several highlights.

One of just two albums to be released by the easier-going American equivalent of Richard & Linda Thompson (without the brooding gloom and biting irony), this set includes some virtuoso folk-blues performances, as well as the version of "Brazil" made famous in Terry Gilliam's movie of the same name. Though the ten tunes here are all covers, Geoff & Maria Muldaur treat each as if molded from clay of their own making, just as they had old traditional numbers as members of the Jim Kweskin Jug Band. It's probably no coincidence that this album would eventually find its way to Joe Boyd's Hannibal label. It's a collection that suggests the Richard & Linda Thompson albums he would release throughout the '70s. Although it's often difficult to find, many fans will find Pottery Pie more than worth the money and effort.

With Painting Signs, Eric Bibb makes a fine case for blues as a music of introspection, warmth, and supreme nuance. Easily his most mature album to date, Painting Signs continues Bibb's formula of socially aware songs performed from an acutely personal point-of-view; standout tracks "Don't Ever Let Nobody Drag Your Spirit Down" and a cover of "Hope in a Hopeless World" hammer home his message of individual freedom and the responsibilities that accompany it. (It's no coincidence that Pops Staples, to whom Bibb dedicates this album, once recorded the latter song.) That's not to say Painting Signs is overly didactic or, indeed, "heavy" in any way; even the most serious songs here, like the plea for peace and unity "Got To Do Better," are leavened by a musical backdrop that's soulful and immediately accessible. Gospel-leaning backing vocals by Linda Tillery and her Cultural Heritage Choir help flesh out several cuts, and robust accordion fills by Bibb's longtime accompanist Janne Petersson add a subtle Louisiana flavor to the rolling, propulsive "Kokomo" and, to surprisingly good effect, the deep-grooved version of Jimmy Reed's "Honest I Do."
