Here’s a 13-minute jam for your morning enjoyment. It’s the title track from The Butterfield Blues Band’s second album, released in 1966. It was recorded at Chess Studios at 2120 South Michigan Avenue in Chicago and features guitar solos by Elvin Bishop (first) and Mike Bloomfield (second) with a harmonica solo by Paul Butterfield sandwiched in between. Mark Naftalin plays keyboards, Jerome Arnold plays bass, and Billy Davenport plays drums. The idea for the song came to Mike Bloomfield during an LSD trip in 1965, when he "had a revelation into the workings of Indian music." The picture on the front of the album was taken at Chicago’s Museum of Science and Industry.
