Joan Jett acquired that net worth as a rock guitarist, singer, and songwriter for the 1980′s rock band Joan Jett and the Blackhearts and the group The Runaways. Born Joan Larkin on September 22, 1958, in Philadelphia, Pennsylvania, Jett became a prominent name in the world of rock&roll and punk mainly thanks to her work with Joan Jett & the Blackhearts. At the age of 13 she got her first guitar, while two years later she has already entered the music business as a founding member of the punk-pop band The Runaways. The all-female group produced five albums from 1975 until they separated in 1979. This led Jett to move to New York where she pursued a solo career. Teaming up with producer Kenny Laguna, Jett saw the independent release of her self-titled debut album in 1980. The well-sold album earned her contract with Boardwalk Records, who reissued the album under the title Bad Reputation. Next, she formed the Blackhearts, a group including guitarist Ricky Byrd, bassist Gary Ryan, and drummer Lee Crystal. The end of 1981 saw the release of her greatest success, the album I Love Rock-n-Roll, which sent her into the Top Ten. They produced other popular recordings throughout the 1980s, including Do You Want to Touch Me, Crimson and Clover, Light of Day, I Hate Myself for Loving You and Love Is All Around. Three of her albums have been certified Platinum or Gold by the IRA. Creating consistent music from her first band to her hit-making days with the Blackhearts, she has been often referred to as the Queen of Rock 'n' Roll during her career.
