By the end of the 70's Zappa was looking for a second front man. It should be someone with talent and presence of a Napoleon Murphy Brock but on the other hand totally different. Anyway, he should take the substantial vocal parts Zappa wanted to restrain from.
The singer and guitarist met Frank Zappa in 1977 at a concert in the backstage area. Zappa engaged him and so he's been a band member since 1988, except the tours in 1981 and 1982. This was the time when such succinct albums as Joe´s Garage, Thing-Fish, Tinseltown Rebellion und You Are What You Is developed, with his expressive and unmistakable voice.
On Joe´s Garage he can „only“ be heard as singer, later then as guitarist, too. He can't say which song has impressed him most or which has been the most complicated one. They are all different and belong to such various categories so it's impossible for him to decide.
So Ike Willis is the one who's been for the longest time in Zappa's permanently changing line-ups. Ike had the impression that when they met Zappa had lost the fun, although he's been enormously productive. Fortunately that changed from album to album and Zappa got back to his motto "The stupider it is, the better we like it!".
