The concert marks for John Mayall's band a return to the standard quartet format, after some ten years with twin lead guitars. Playing alone now gives Coco Montoya the opportunity to present his own approach to the music which sounds more British blues. Mayall, who was soon to turn 60 years old, is also in top form as pianist, harmonica player and singer.
Eight of the nine tracks are songs from the album Wake Up Call released earlier the same year. Among them, "Nature's Disappearing" was already a rerecording of a song from USA Union (1970). "The Bear" is the exception which comes from Blues from Laurel Canyon, a 1968 album.
