Rock historians view the Bangles as one of the greatest all-female bands ever, lauding the L.A.-based quartet for its inventive incorporation of '60s folk rock, sunny SoCal harmonies and Beatles/Byrds/Beach Boys/Big Star godhead into a sound all its own - beguiling, frequently bittersweet, but always life-affirming; a canny merger of art and commerce. Theirs was a rags-to-riches story, from the band's beginnings in L.A.'s Paisley Underground scene through their reign as the smart-pop princesses of the 1980s.
