LOS ANGELES » Lee Dorman, the bassist for psychedelic rock band Iron Butterfly, has died at age 70.

Orange County sheriff’s spokeswoman Gail Krause says Dorman was found dead in a vehicle Friday morning. A coroner’s investigation is under way, but foul play is not suspected.

Krause said Dorman may have been on his way to a doctor’s appointment when he died.

Iron Butterfly was formed and rose to prominence in the late 1960s. Its second album, “In-A-Gadda-Da-Vida,” sold more than 30 million copies, according to the band’s website. The title track’s distinctive notes have been featured in numerous films and TV shows including “The Simpsons,” ”That ’70s Show” and in the series finale of “Rescue Me.”

Douglas Lee Dorman was born in September 1942 and had been living in Laguna Niguel, a coastal city in Southern California, when he died.

A message sent through the band’s website was not immediately returned.
