In the pieces that made up Joe's Garage, Zappa used a wide variety of instruments. He used a synthesizer, drums, electric instruments (guitar/piano), and potentially more instruments. It is difficult to identify all the instruments because a synclaire could be producing sounds that may sound similar to instruments. There are highly offensive lyrics and interesting (not pretty) singing.

When I first started listening to the pieces from Joe's Garage, I was having great difficulty getting over the lyrics. They lyrics are loud, offensive, and some of the voices are slightly obnoxious and I felt that they took away from the music. Since this album was written to be a Rock Opera, I had to move past the lyrics and the singing, and look at the piece
