1. Incubus is a five-man alternative rock band formed in 1991, based in Calabasas, California. Members include Brandon Boyd (vocals and percussion), Mike Einziger (guitar), Ben Kenney (bass), Jose Pasillas II (drums) and DJ Chris Kilmore (turntables). Former members of the band include Gavin Koppel (a.k.a. DJ Lyfe) (turntables) and Alex Katunich (a.k.a. Dirk Lance) (bass). The band's name may seem a peculiar choice to fans, as an incubus is a type of demon that, in mythological lore, comes in the night and has sex with women while they are sleeping; it seduces them in their dreams The story behind the name is that the band needed to think of a name hours before their first show and, after a few failed choices, Mike looked in a dictionary and chose "Incubus" almost at random. Mike says that the name was chosen because it sounded silly; Brandon holds that it was chosen because they were teenagers and the definition had the word "sex" in it. "We really didn't want to rape women in their sleep. But, we were fifteen and it seemed harmless to us then, and we never changed it," says the band. Incubus has also tried to cover their tracks by stating that they got the name from a plant in South America that produces mind-altering chemicals. However, the fabled Incubus plant does not actually exist.

Incubus has released six albums and two EP's to date.
