One of pop's best-loved and most influential cult bands, Sparks grew out of the minds of brothers Ron and Russell Mael. The combination of Russell's formidable vocal range, Ron's impressive keyboard skills, and their vividly witty songwriting defined their music as it changed over the years -- which it did often. When they emerged in the early '70s, their theatricality fit in with the glam rock scene, with albums like 1972's A Woofer in Tweeter's Clothing and 1974's Kimono My House earning them a strong following in the U.K. Just a year later, Sparks were at the forefront of the power pop movement with 1975's Indiscreet; by the end of the decade, they were electronic pop pioneers, working with Giorgio Moroder on 1979's No. 1 in Heaven.
