Album: Big Star, Keep an Eye on the Sky, (Rhino)

Ahead of the reissue of the Memphis power-pop superheroes' first two albums comes this four-disc set, a rattlebag of bits, bobs and things that were never meant to see the light of day. It is, of course, an academic exercise only to be properly appreciated by scholars.

And the scholar in you will thrill less to the alternative mixes of familiar songs than to the demos and pre-Star efforts, which leak the same admixture of sincerity, reverence to masters (Beatles mostly) and frazzled energy. Beautiful in small parts.
