Cassandra Wilson's swinging for her own creative fences this time. The sultry, gentle, acoustic guitars on her last five recordings have been largely jettisoned for a more keyboard-and percussion -friendly approach – which includes lots of programming and loops. To that end, she's enlisted flavor-of-the-year producer T-Bone Burnett and keyboardist Keith Ciancia. This pair hired a stellar group of players that include drummer Jim Keltner, bassist Reginald Veal (a near-constant here), guitarists Colin Linden and Marc Ribot, and programming whiz Mike Elizondo. Mike Piersante plays "keypercussion" (read: drum loops), Jay Bellerose and Bill Maxwell also contribute kit work. Keb Mo' guests on a track.

After a slow start, Cigarettes After Sex saw their fortunes swiftly reversed by a whirlwind of YouTube hits. Although they formed in 2008, CAS waited nearly a decade to release their debut record, and rather fittingly it unfolds at a lethargic pace. The music that Greg Gonzales and his fellow bandmates produce is slowcore in the extreme. The shimmering guitars, placid percussion, and wistfully delivered vocals also reveal their debt to dream pop and shoegaze. More than anything, early supporters of the band have praised Gonzales' unashamed sentimentality and dyed-in-the-wool romanticism. You don't have to venture beyond the opening track to experience his hazy passion.

Spooky Two is this British blues-rock band's pièce de résistance. All eight of the tracks compound free-styled rock and loose-fitting guitar playing, resulting in some fantastic raw music. With Gary Wright on keyboards and vocals and lead singer Mike Harrison behind the microphone, their smooth, relaxed tempos and riffs mirrored bands like Savoy Brown and, at times, even the Yardbirds. With some emphasis on keyboards, songs like "Lost in My Dream" and the nine-minute masterpiece "Evil Woman" present a cool, nonchalant air that grooves and slides along perfectly.

Boomerang's eponymous 1971 debut also proved to be their last (though a shelved second album remains stashed away somewhere), and its surprisingly stripped-down and unfettered blues-rock approach will probably surprise those familiar with vocalist/organist Mark Stein's earlier work with psychedelic overlords Vanilla Fudge. Clearly inspired by the white-knuckled intensity of Led Zeppelin's first two albums, economic hard rockers like "Juke It," "Cynthia Fever," and "The Peddler" attempted to deliver the same thrilling brand of sheer power masking barely reigned-in virtuosity.

The New Colony Six started out as one of the better garage bands to come out of the Midwest in the mid-'60s, playing tough British Invasion-style rock & roll (their "At the River's Edge" made it onto the Nuggets box set), and they later evolved into a surprisingly sophisticated and skillful pop group that scored nationwide hits with the singles "Love You So Much" and "Things I'd Like to Say." However, this collection of odds and ends doesn't quite play to either side of the band's personality; in fact, most of the 24 songs aren't actually by the New Colony Six, with 11 tunes by the Raymond John Michael Band (which featured three NC6 alumni, singer Ray Graffia, drummer Chick James, and keyboard man Craig Kemp) and one each by Junior and Graffia, both latter-day Ray Graffia projects…
