This is the first of two super session albums that Chess produced in the late '60s. Time has been a bit kinder to this one, featuring Muddy, Bo Diddley and Little Walter, than the one cut a year later with Howlin' Wolf standing in for Walter. It's loose and extremely sloppy, the time gets pushed around here and there and Little Walter's obviously in bad shape, his voice rusted to a croak and trying to blow with a collapsed lung. But there are moments where Bo's heavily tremoloed guitar sounds just fine and the band kicks it in a few spots and Muddy seems to be genuinely enjoying himself. Granted, these moments are few and way too far between, but at least nobody's playing a wah-wah pedal on here.
