This release's target market (besides Smog completists) might be budding ethnomusicologists, because it provides a concise study of Bill Callahan's development as a songwriter over the course of a decade or so, a "then and now" comparison. Callahan begins by offering a snapshot from his 2000 release, Dongs of Sevotion. The excellent "Strayed," a Leonard Cohen-like crooning confessional, showcases a style Callahan has been slowly perfecting since 1993's Julius Caesar. Then gears shift completely, and Callahan gives the listener a glimpse at some of his "baby pictures," a reissue of the eight-song instrumental Cow EP, originally released on Callahan's own Disaster label in 1989. The juxtaposition is interesting, the subtle and retrained title track paired with the raucous and clanging Cow tracks, but hardcore Smog fans will already be familiar with the contrast and not need the lesson.
