This four-disc set offers an outstanding overview of the career of Western swing legend Bob Wills and his band, the Texas Playboys. You hear their sound in the early days, when the band was small and focused on guitar and fiddle, and you hear the band develop into a highly sophisticated, horn-heavy, honky-tonking, hard-swinging country jazz band that could heat up a dance floor more quickly and comprehensively than just about anyone else. The sound quality on this set is outstanding, and easily rivals that of the much more expensive Bear Family box that is its most obvious competition.
