In the late 60's and early 70's the US and the world witnessed a massive wave of rock festival's. The most famous are Monterey (the first) and Woodstock (possibly the biggest) but one of the last in this wave was California Jam (known as the 'Woodstock of the West") held at the Ontario Motor Speedway in Ontario, California on April 6, 1974
A massive 200,000 fans attended and unlike Woodstock the concert was not planned for release as a film or sound recording.
The festival featured Rare Earth, Earth, Wind and Fire, Eagles, Seals & Crofts, Black Oak Arkansas, Black Sabbath, Deep Purple and Emerson, Lake and Palmer
Emerson, Lake and Palmer were top of the bill: Emerson played a grand piano spinning end-over-end 50 feet above ground level
Oscar Peterson, jazz master was so impressed he telephoned none other than Count Basie to watch.
Deep Purple's chrisitened David Coverdale at the festival and Glenn Hughes. Ritchie Blackmore was kind enough to throw multiple guitars out into the audience and created a fire dousing the speakers with petrol and lighting them
