Best known for putting together the all-girl rock group The Runaways back in 1975 (an event that was subsequently put to film starring Kristen Stewart, Dakota Fanning and Michael Shannon), Fowley was a huge name in the world of 70s and 80s punk having produced three of the band's albums 'The Runaways', 'Queens of Noise' and 'Waitin' for the Night' as well as managing them.

It was reported by Billboard in September last year that Fowley's cancer struggles had reignited the bond between him and Runaways front-woman Cherie Currie, despite the pair having been embroiled in a legal battle over royalties for most of their subsequent careers. Apparently the singer invited her old friend into her home in order to take care of him. 'Kim's fiancee, Kara Wright, called me to let me know about his health, and we agreed a change of environment was what he needed', she revealed at the time. 'It's draining, yes, but I'll always step up. It's who I am.'

In his long career, Fowley has also worked with the likes of  Flash Cadillac & the Continental Kids, The Innocents, Paul Revere and the Raiders, Alice Cooper, KISS and, most recently Ariel Pink on his 2014 album 'pom pom'. Aside from writing songs, producing and managing, he has also released his own solo work including the renowned 1968 album 'Outrageous'.
