Previously issued on DVD in 2006, the project features the band's appearance at California Jam, a festival co-headlined by Deep Purple and Emerson, Lake & Palmer that was held at the Ontario Motor Speedway in Ontario, California on April 6, 1974.

The Deep Purple lineup of Ritchie Blackmore (guitar), David Coverdale (vocals), Glenn Hughes (bass), Jon Lord (keyboards) and Ian Paice (drums) rocked through a set of songs from "Burn", as well as classics like "Space Truckin'" and "Smoke On The Water."
