Lee Dorman, bass guitarist for the 1960s psychedelic rock band Iron Butterfly, died at age 70 on Dec. 21, 2012.
He was found dead in his car near his home in the Southern California town of Laguna Niguel. Coroner's officials said he died of natural causes, adding that he was under the care of a doctor and may have been on his way to an appointment before he passed away, the Associated Press reported.
Dorman was born in St. Louis, Missouri in 1942. He moved to California in the 1960s. He then joined the San Diego-based band Iron Butterfly, which rose to fame in the later part of the decade with singles such as "In-A-Gadda-Da-Vida -- the group's biggest hit, 'Soul Experience" and 'Easy Rider.' The band, including Dorman, had been performing regularly as recently as May 2012.
