The Penguin Guide to Blues Recordings describes the album as “one of the few occasions when younger musicians partnered [Hooker] to wholly beneficial effect.”[2] This was the last studio album to feature harmonica player, guitarist and songwriter Alan Wilson, who died in September 1970 (1970-09) from a drug overdose.

The photo on the album cover was taken after Wilson's death, but his picture can be seen in a frame on the wall behind John Lee Hooker.

The person standing in front of the window, filling in for Henry, is the band's manager, Skip Taylor.
