As a rock band, Oingo Boingo started as a ska and punk-influenced new wave octet, achieving significant popularity in Southern California. During the mid-1980s, the band changed line-ups and adopted a more pop oriented style, until a significant genre change to alternative rock in 1994. At that point, the name was shortened to simply Boingo and the keyboardist and horn section were dropped. The band retired after a farewell concert on Halloween 1995, for which they reverted to the name Oingo Boingo and readopted the horn section.
