All but one of these 19 tracks were recorded in December, 1964, as Paul Butterfield Blues Band's projected first LP; the results were scrapped and replaced by their official self-titled debut, cut a few months later. With both Michael Bloomfield and Elvin Bishop already in tow, these sessions rank among the earliest blues-rock ever laid down. Extremely similar in feel to the first album, it's perhaps a bit rawer in production and performance, but not appreciably worse or different than what ended up on the actual debut LP. Dedicated primarily to electric Chicago blues standards, Butterfield fans will find this well worth acquiring, as most of the selections were never officially recorded by the first lineup (although different renditions of five tracks showed up on the first album and the What's Shakin' compilation).
