American Routes takes a peek at the producers, sidemen and record company moguls who can make or break a record. New Orleans saxophonist Harold Battiste talks about playing with Ornette Coleman, acting as music director for Sonny & Cher, and founding his own jazz and blues label. Plus the inside story on Muddy Waters’ much maligned, but imaginative, 1968 album Electric Mud, by producer Marshall Chess and musicians Pete Cosey and Louis Satterfield.
