Joan Jett and the Blackhearts are an American rock band led by artist Joan Jett. After The Runaways split in 1979, Jett pursued a solo career to explore the same aggressive punk style and met Kenny Laguna. Jett soon released her self-titled debut. Shortly after that, with Kenny's assistance, Joan formed the backing group "The Blackhearts" with three obscure New York area musicians: Gary Ryan on bass, Eric Ambel (replaced shortly thereafter by Rick Byrd) on guitar and Lee Crystal on drums.
