Lee Dorman, bassist for proto-metal rockers Iron Butterfly, died today at his home in Orange County, Calif.. He was 70.
The county coroner's office tells E! News that Dorman, who had a history of heart trouble, was found in his car at around 9 a.m., dead of what appeared to be natural causes.
Iron Butterfly's biggest hit was the 1968 jamfest "In-A-Gadda-Da-Vida," off the album of the same name, and Dorman's booming bass figures prominently in the classic tune. Buoyed by its 17-minute title track, more than 30 million copies of In-A-Gadda-Da-Vida have been sold over the years.
