Ike Willis (November 14, 1951) is an American singer and guitarist who was a regular sideman for Frank Zappa, first joining Zappa's band for the fall 1978 tour and remaining in the band for several years. He did not tour with Zappa in 1981 and 1982 for personal reasons, but returned to touring with Zappa for his final two tours in 1984 (which Zappa intended at the time to be his final tour) and 1988. He currently tours with the Frank Zappa tribute bands Bogus Pomp, Ossi Duri, Project/Object and Ugly Radio Rebellion. He's also performed several times with the Brazilian Zappa cover band, The Central Scrutinizer Band, The Muffin Men, and with the Italian band Elio e le Storie Tese. He is most recognized for his involvement in Zappa records such as playing Joe in Joe's Garage, providing vocals on Tinsel Town Rebellion, You Are What You Is, and The Man from Utopia, and as the title character and narrator in Zappa's off-Broadway-styled conceptual musical Thing-Fish.
