Musicians and playwrights have made reference to Scientology on some of their work, with some pieces treating the topic in a negative light by their references, and others in a positive manner. Frank Zappa's 1979 concept album/rock opera "Joe's Garage" lampoons Scientology in the song "A Token of My Extreme". Scientologist Chick Corea has made reference to Scientology in his work, and two of his albums were influenced by L. Ron Hubbard novels. Maynard James Keenan of the metal band Tool, has been critical of Scientology, and the 1996 song "Ænema" contains a negative reference to L. Ron Hubbard. Both Scientology and the life of its founder L. Ron Hubbard were addressed in the 2003 Off-Broadway musical, "A Very Merry Unauthorized Children's Scientology Pageant". The play took a tongue-in-cheek look at both Hubbard's life and the history of the Church, and received an Obie Award in 2004.
