Beyond the Valley of the Dolls (1970)

A hip and happenin' all girl rock group head to LA to claim lead-singer Kelly's inheritance and make it (and make it) in LA. They immediately fall under the spell of rock'n'roll Svengali, the 'Teen Tycoon' of rock Ronnie 'Z-Man' Barzell, and other rapacious Hollywood party types as lustful porno actress Ashley St Ives, ravenous lesbian Roxanne and shady lawyer Porter Hall. Soon the girls fall into a morass of drugs and deceit as their recording success soars. It takes several tragedies to make them stop and think... but is it too late?
