Richard Elfman founded the theatrical troupe The Mystic Knights of the Oingo Boingo. In 1978 the remnants of the Mystic Knights formed together under lead singer Danny Elfman as the band Oingo Boingo. The hyperkinetic ska-flavored New Wave band is characterized by their manic live performances and eclectic range of songs; Elfman and the band performed for a remarkable twenty years.
