Brothers Ron and Russell Mael rose from Los Angeles as masterminds of a theatrical sound that rolls playfully from pop to hard-edge rock to disco-era electronic tunes with Giorgio Moroder ("No. 1 in Heaven"). Russell is historically the excitable falsetto frontman and Ron the twitchy dude behind the keyboard in the Charlie Chaplin mustache. Their flamboyant signature albums, Kimono My House from 1974 and 1975’s Indiscreet, were despised by American critics at the time, and beloved by an international cult that has rarely faded through the decades. Sparks arrive at Coachella to perform a stripped-down stage show called "Two Hands One Mouth," with the Maels alone onstage.
