Oingo Boingo was an American new wave band, best known for their hits "Dead Man's Party" and "Weird Science". They are noted for their soundtrack contributions and high energy Halloween concerts, as well as their mixture of styles, including ska, pop, rock, and world music. The band was founded in 1972 as The Mystic Knights of the Oingo Boingo, a performance art group. The band was led by songwriter/vocalist Danny Elfman, who has since achieved success as a composer for film and television. The group's format changed twice. In 1979, it reshaped from a semi-theatrical music and comedy troupe into a ska-influenced new wave octet and shortened their name to Oingo Boingo. In 1994 the band shortened their name again to Boingo, following a shift away from the use of horns and synthesizers in favor of more guitar-oriented rock that began in the late 1980s. The band retired after a farewell concert on Halloween 1995, for which they reverted to their earlier style and to the name Oingo Boingo.
