David Crosby is more than just a third of Crosby, Stills & Nash (and sometimes Young). He was in the Byrds and has worked with other bands. These three CDs bring together Crosby's best works as a songwriter or co-writer. The Byrds' "Eight Miles High" and CS&N's "Guinnevere," "Deja Vu" etc., are some of Crosby's strongest works. There are also duets with Graham Nash, filled with Crosby's joyful tenor. One cut on this 52-track collection is "Hero," which he recorded with Collins in 1993, a poignant, powerful examination of the fine line between hero and criminal. The third disc is previously unreleased works. — S.I.

THE DOORS; "Perception (40th Anniversary Box)" (Rhino/Elektra) ***

After lead singer Jim Morrison died in 1971, surviving Doors members released two studio albums without him: "Other Voices" and "Full Circle," which have long been out of print, and which continue to be ignored in this latest box set. Still, this six-CD, six-DVD set, with new remasters of the Morrison-fronted albums, does feature harmonies and instrumental versions that were mixed out of the originals, along with such rarities as the complete Morrison theatrical poem "The Celebration of the Lizard," concert footage, music videos and slide shows. — S.I.

BUDDY GUY; "Can't Quit the Blues" (Silvertone/Legacy) ****

Guy influenced everyone from John Mayer to Eric Clapton, and this collection is a carefully produced mix of sad songs and foot-stompers: "Hoodoo Man Blues," "In the Wee Hours," "Mustang Sally" — three discs worth. Plus a terrific 90-minute documentary on a DVD that includes performances ranging from 1974-2004. — C.H.

BRUCE HORNSBY; "Intersections 1985-2005," (RCA/Legacy) ****

Bruce Hornsby has always said he is a jazz pianist with punk attitude. He just plays music and doesn't care what others think, and has for more than 20 years. The set documents Hornsby's rise up the charts, his break from hitsville and his joining up with everyone from the Grateful Dead to Branford Marsalis to B.B. King. Four CDs of Top 40 hits, two filled with fan requests and a 23-track DVD make this the most comprehensive Hornsby collection ever. — S.I.

WAYLON JENNINGS; "Nashville Rebel" (RCA/Legacy) ****
