A very rare white label promo copy of "Muddy Waters Sings Big Bill," Muddy's 1960 tribute to Big Bill Broonzy (and Muddy's 2nd LP.) Chess promo albums are extremely scarce, and this one is a beauty; with a NM-/EX+ disc and NM- cover. The disc looks barely played and has a few scuffs, but sounds great. The cover is the cleanest we've ever seen, with a DJ stamp on the back, and 1/3" split on the bottom center spine. A great copy of a classic blues album.
