Joan Jett at L.A. Pride Festival at West Hollywood Park

When the Runaways disbanded in 1979, singer-guitarist Joan Jett was already considered washed up at the age of 19. Undeterred by the terminally sexist music industry and often-condescending media critics, she reinvented herself with a solo career that soon produced such classic anthems as “Bad Reputation” and “I Love Rock ’N Roll,” which was a No. 1 hit in 1982. With a sound that draws equally on glitter, punk and bubblegum, her music attracts an unusually diverse range of fans. Like Cheap Trick, she has the ability to cross over into the mainstream without being considered a sellout. How many other rock stars would have been hip (and prescient) enough to produce the Germs’ G.I. album in 1979 and star alongside Michael J. Fox in the 1987 film Light of Day — without losing her credibility? Her 2006 CD, Sinner, is a typically unpretentious affair with no-nonsense rockers like “Naked” and a juiced-up cover of Sweet’s “A.C.D.C.,” and she opens up her big, bad black heart with a touching version of the Replacements’ ode to freaks of all genders, “Androgynous,” the perfect theme song for this weekend festival. Sunday’s lineup includes Jett’s thrilling new pop-punk protégées Girl in a Coma. 647 N. San Vicente Blvd., W. Hlywd. www.lapride.org. (Falling James)
