Kim Fowley, the producer and songwriter best known as the infamous manager of The Runaways, has died, according to reports that first appeared in Rolling Stone. He was 75. A cause of death has not been released, but Fowley had been battling cancer for several years before his death.

Born in 1939 in Los Angeles, Fowley began working in the music industry in 1959, when he produced “Charge” by The Renegades. Fowley remained active throughout the 1960s, working with the likes of Paul Revere & The Raiders, Gene Vincent, and The Seeds, all while pursuing a solo career. He continued working as a songwriter in the 1970s, during which he wrote songs for Kiss, Alice Cooper, Blue Cheer, and The Modern Lovers. However, he found his greatest success with The Runaways, the band that he helped start when he introduced Joan Jett to drummer Sandy West in 1976. With the addition of Cherie Currie (vocals), Lita Ford (guitar), and Jackie Fox (bass), the Runaways scored a hit with their debut single “Cherry Bomb,” which was penned by Fowley and Jett. Fowley acrimoniously parted ways with the band in 1977.

In recent years, Fowley remained active in other pursuits, including filmmaking and a radio show in Steven Van Zandt’s SiriusXM channel. He was still active in music, appearing in the video for Beyonce’s Haunted and writing some songs for Ariel Pink’s 2014 album pom pom.
