Rising Sons was a Los Angeles, California-based band founded in 1964. (More from Wikipedia)
The 1960’s psychedelic/progressive rock band Spirit formed in Los Angeles in 1967, growing out of an earlier L.A. band called the Red Roosters. The inclusion of Randy California’s stepfather Ed Cassidy (drums) brought the band an added dimension that was missing from most 1960’s rock bands: Besides being much older than the other bandmembers, Cassidy cut his teeth playing in numerous jazz bands including stints with Cannonball Adderley, Gerry Mulligan, Roland Kirk, Thelonious Monk, and Lee Konitz. Ed Cassidy was also a founding member of the 1964 band Rising Sons that also included Taj Mahal and Ry Cooder.
