A blues and rock keyboardist who spent his career making other artists' records better, co-producing albums for Percy Sledge, Charlie Musselwhite, and James Cotton and helping shape Bob Dylan's version of Curtis Mayfield's "People Get Ready." His playing and production work sat at the connective tissue of Chicago blues and the rock scene it fed, the kind of contribution that rarely gets a headline but is heard on records that did.
