This follow-up to last year's Volume 1 features mostly B-side tracks ("Torn Apart," "Without You Here") and covers (INXS' "Don't Change," Tom Petty's "American Girl," Fleetwood Mac's "I Don't Want to Know"). Of particular interest is a demo of the Dolls' smash-hit "Iris." Disc 2 is a DVD of the band's videos ("Here Is Gone," "Let Love In," "Iris" and "Black Balloon," among others), as well as six concert videos from the band's 2007 appearance at Colorado's Red Rocks Amphitheatre. — Todd Curtis

HEART; "Playlist: The Very Best of Heart" (Epic/Legacy) ** 1/2

Throughout Heart's career, the songs of Ann and Nancy Wilson have been collected in a few "greatest hits" compilations. This one is about the same playlist with "Barracuda," "Straight On," "Even It Up" and "Dog and Butterfly." But the live versions of "These Dreams," "Crazy on You," "Magic Man" and the studio versions of "Johnny Moon," "Love Alive" and "Mistral Wind' are nice additions. — S.I.

HERBIE HANCOCK; "Then and Now: The Definitive Herbie Hancock" (Verve) ****

Herbie Hancock will always be known for his pioneering MTV single "Rockit." The song became a favorite among suburban breakdancers in the 1980s. But there was more to this eclectic musician than pop hits. "Then and Now: Definitive Herbie Hancock" shines a rather large spotlight on the man's multifaceted jazz musicality. "Maiden Voyage," "Wiggle Waggle," "St. Louis Blues" with Stevie Wonder, two versions of Joni Mitchell's "River," one with Corinne Bailey Rae and one with Mitchell herself, and his take on Nirvana's "All Apologies" shows how hip this cat can be. — S.I.

TOMMY JAMES AND THE SHONDELLS; "40 Years: The Complete Singles Collection (1966-2006)" (Rhino) *** 1/2

Most everyone knows "Mony Mony," "Hanky Panky" and "Crimson and Clover," by Tommy James and the Shondells. In this two-CD, 48-track release, all of James' hits are in one place. And to audiophiles' delight, the songs that were recorded in mono are still remastered in mono. "I Think We're Alone Now," "Crystal Blue Persuasion," "Glory Glory," and the bonus track "Long Ponytail" are songs that span the singer's 40-year career. — S.I.

GEORGE JONES; "Burn Your Playhouse Down: The Unreleased Duets" (Bandit) ***

While not a compilation of hits, "Burn Your Playhouse Down" is a collection of rare George Jones tracks where the "Ol' Possum" sings and plays with the likes of Dolly Parton ("Rockin' Years"), Vince Gill ("Selfishness in Man"), the Rolling Stones' Keith Richards ("Burn Your Playhouse Down"), the Dire Straits' Mark Knopfler ("I Always Get Lucky With You") and, of course, Tammy Wynnette ("Lovin' You, Lovin' Me"). There are more and they are good. — S.I.
