Alan Simon is a French folk-rock musician and composer, best known for his rock operas performed with noted rock musicians guesting. Simon is associated with Breton Celticism, and his most ambitious works are typically on themes linked to Celtic myth and history. Simon achieved fame with his rock opera Excalibur, La Légende des Celtes (Excalibur, The Legend of the Celts) (Sony) in 1999, of which he was both songwriter and producer. The first part of an intended trilogy, Excalibur blended musical styles and was performed by Roger Hodgson (ex-Supertramp), Fairport Convention, Dan Ar Braz, Tri Yann, Angelo Branduardi, Didier Lockwood and Gabriel Yacoub.

Rick Derringer tried a variety of different things in the 1980s, '90s, and 2000s. The singer/guitarist recorded his share of middle of the road pop/rock and adult contemporary albums, and he even recorded an instrumental jazz-pop/smooth jazz album that had George Benson-ish leanings (2002's Free Ride). But Derringer, who turned 61 in 2008, has a way of going back to blues-rock and hard rock – which is exactly what he does on Knighted by the Blues. Granted, this 2009 release wasn't recorded with blues purists in mind; not everything on Knighted by the Blues adheres to the traditional 12-bar format.

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.

Epic's The Essential Stevie Ray Vaughan and Double Trouble gathers two discs' worth of the late blues guitarist's work, including many live performances and a few tracks with the Vaughan Brothers. The collection presents Vaughan's material in roughly chronological order, from the 1980 live recording "Shake for Me" to 1989's "Life by the Drop." It also touches on most of Vaughan's definitive songs and performances, including "Tightrope," "Wall of Denial," "Couldn't Stand the Weather," and "Cold Shot," and live versions of "The Sky Is Crying," "Superstition," and "Rude Mood/Hide Away." Though this album doesn't offer anything that hasn't already been released in some form or another, it does go into slightly more depth than several of the other Stevie Ray Vaughan retrospectives by presenting both his greatest studio hits and some of his best live work.

Debussy's Études are really the only set that deserves to be put beside Chopin's. What makes them so special? Like his, they are truly "practice pieces," systematically exploring various aspects of keyboard technique. But at the same time, they are poetic works of art, full of fantasy, charm, and musical invention. Uchida's recording is almost universally regarded as the finest version of these works to appear in modern times. Her playing combines effortless virtuosity with pianistic precision, keeping the music's artistic and pedagogical tendencies in a state of exquisite tension. This disc also established Uchida's claim to be recognized as one of the most interesting and talented pianists now active. You need to hear it.

After 35 years and the release of over 2800 contemporary blues tracks, it's safe to say that Bruce Iglauer's Alligator Records is the world's premier blues label, particularly if sheer numbers are factored in, and while the label's releases tend to sound mind-numbingly similar sometimes, this two-disc overview of Alligator's history shows how much raw vitality the blues still has in its tank. Alligator Records 35X35, arranged chronologically and featuring a selection drawn from each of the artist's debut albums with Alligator, gets rolling right where it all began, with Hound Dog Taylor's "She's Gone" from 1971, and marches through to 2004, closing the second disc with a stunning version of "See That My Grave Is Kept Clean" (here called "A Dying Man's Plea") by the great Mavis Staples, who makes clear the deep affinity of gospel to the blues, or vice versa, since the two forms philosophically complete each other, the way Saturday marches straight into Sunday.
