Isaac Hayes has died. It’s easy to remember him for South Park and the Scientology spat that followed, but his work as a session musician and writer for Stax and his own, darker sound made him one of the cornerstones of seventies soul. Here is Walk On By, the opener from his breakthrough album, Hot Buttered Soul. Get the whole album – four 10 minute workouts of dark, brooding, groove driven soul that hasn’t been bettered. This video doesn’t do it justice, but it will give you a taste.
