California Jam, a rock festival that took place April 6, 1974, at Ontario Motor Speedway, drew 200,000 people. My Sunday column hits some of the high points. Allen Pamplin of the California Jam Fan Club on Facebook sent me multiple photos. Here are 10. The two above originally came from Alan Lancendorfer.
The above four are uncredited. The bottom four were contributed by promoter and emcee Don Branker. Rare Earth, the day’s first band, is performing in the next to last image. A roadie adjusts a microphone in the final image.
