 It was one of the first to feature their third line-up, which included vocalist David Coverdale and bassist/vocalist Glenn Hughes.At the end of the show, guitarist Ritchie Blackmore first attacked one of the network's video cameras (which had been getting between him and the audience) with his guitar, and then had his amplifiers doused with gasoline and set on fire, which caused an explosion.Most of this concert was broadcast over 4 weekends in April 1974 on KLOS-FM ABC-TV Stereo Simulcast, along with other California Jam artists.
