LOS ANGELES – Authorities say Lee Dorman, the bassist of psychedelic rock band Iron Butterfly, has died at age 70.

Orange County Sheriff’s Department spokeswoman Gail Krause said Dorman was found dead in a vehicle Friday morning. An investigation is under way but foul play is not suspected.

Iron Butterfly rose to prominence in the late 1960s. Its second album, “In-A-Gadda-Da-Vida,” sold 30 million copies.
