Ed Cassidy was born in Harvey, Illinois, a rural area outside Chicago, on May 4, 1923. His family moved to Bakersfield, California in 1931. Cassidy began his career as a professional musician in 1937. He served in the U.S. Navy during World War II, and after his discharge held many jobs before becoming a full-time musician again. At one time in the late 1940s, Cassidy played 282 consecutive one-nighters in 17 states. He worked in show bands, Dixieland, country and western bands, and on film soundtracks, as well as having a brief stint with the San Francisco Opera.
In 1950, Cassidy enrolled at college to get a musical teaching credential. However, after a year, he decided to move to Southern California to meet more jazz musicians and perhaps form a group of his own. During this period, Cassidy performed together with many leading jazz musicians including Art Pepper, Julian Cannonball Adderley, Roland Kirk, Lee Konitz and Gerry Mulligan.
With Taj Mahal and Ry Cooder, Cassidy formed the Rising Sons in 1964. After that, he formed the Red Roosters in 1965, with his young stepson Randy California, Jay Ferguson and Mark Andes. Adding John Locke, they became Spirit in 1967. Cassidy sported a shaved head, which was unusual at that time; always wore black; and instead of the double bass drum kit that was popular at the time, he used a single bass drum, and two large parade bass drums as floor toms. Because California stepped out of the group for a period of time in 1972, following the death of Jimi Hendrix, Cassidy was the only member who played with all various line-ups of Spirit on almost 20 albums over almost 30 years. Spirit finally disbanded following Randy California's death in 1997. Cassidy later performed with Merrell Fankhauser in the Fankhauser Cassidy Band. 
From the mid-1970s, Cassidy also worked as an actor, including live improvisation. He wrote, studied history, and continued to correspond with fans from his residence in Southern California until his death. He died of cancer in San Jose at the age of 89 on 6 December 2012. He is survived by his wife, Beverly; a daughter, Carol Ann Griffith; a son Christian Padriack Cassidy; and several stepchildren and grandchildren.
