As Danny Elfman was growing up in the Los Angeles area, he was largely unaware of his talent for composing. It wasn't until the early 1970s that Danny and his older brother Richard Elfman started a musical troupe while in Paris; the group "Mystic Knights of Oingo-Boingo" was created for Richard's directorial debut, Forbidden Zone (1980) (now considered a cult classic by Elfman fans). The group's name went through many incarnations over the years, beginning with "The Mystic Knights of the Oingo Boingo" and eventually just Oingo Boingo. While continuing to compose eclectic, intelligent rock music for his L.A.-based band (some of which had been used in various film soundtracks, e.g. Ciencia loca (1985)), Danny formed a friendship with young director Tim Burton, who was then a fan of Oingo Boingo. Danny went on to score the soundtrack of La gran aventura de Pee-Wee (1985), Danny's first orchestral film score. The Elfman-Burton partnership continued (most notably through the hugely-successful "Batman" flicks) and opened doors of opportunity for Danny, who has been referred to as "Hollywood's hottest film composer".
