Puscifer is an American rock supergroup formed in Los Angeles by Maynard James Keenan, known as the lead singer of the bands Tool and A Perfect Circle. As Keenan is the only permanent member, he considers the project to be his "creative subconscious." In light of this, Puscifer is considered a pseudonym for his solo work. Puscifer's original name was Umlaut, "a premiere improvisational hardcore band". The name "Puscifer" was first publicized as a fictional band in the first episode of Mr. Show, including Keenan and Adam Jones as members.
