This is an excellent compilation of some of Muddy Waters's lesser-anthologized singles, all of them dating from the late '50s. Some of these were surprisingly hard to acquire in any form until this appeared; the original version of "Got My Mojo Working," and for instance, as well as some of his higher-profile tracks, like "Rock Me," "Trouble No More," "Close to You," and "Don't Go No Further." All of these tracks appear on the Chess Box, so if you have that one, you don't need this one. But if you don't, you do.
