A Southern girl with a ghostly voice, Frazer spent a while fronting Tarnation, a band whose '95 ''Gentle Creatures'' (on 4AD) is a lost classic of ethereal folk-rock that sounds like the Cocteau Twins drifting through a Cormac McCarthy novel. This set of demos functions as an excellent best-of, featuring moony, naked versions of songs from her former band as well as her slept-on 2001 solo debut, ''Indoor Universe.'' ORNITHOLOGY Fans of odd backcountry thrushes should check out Jolie Holland, whose ''Catalpa'' (Anti-) is full of dark waltzes and creaky Cat Power-style purring.
