Jett was the musical muscle in the short lived Runaways, an all-female Glam/Bubblegum band put together by notorious Hollywood scenester Kim Fowley at the tail end of the mid-1970s Glam Rock craze. The band imploded before they had any real success and it wasn't long before the charismatic and talented Jett was fronting a hard rocking combo. The leather-clad, Gibson-wielding singer-songwriter and three guys backing her toured incessantly before putting out the sublimely rocking "I Love Rock and Roll." It became a monster hit -- and one of Jett's signature songs. Jett and the Blackhearts were an on-again/off-again chart presence until the late '80s, and in the late '90s Jett went solo. She is revered as a spiritual godmother of the Riot Grrrl movement.
