One Size Fits All is a 1975 tour de force "rock" album from Frank Zappa and The Mothers of Invention. It is the last Zappa album to feature the name The Mothers of Invention. A Quadraphonic version of the album was planned and advertised, but never came to pass.
This Zappa record was the last to feature one of the most highly-regarded versions of The Mothers of Invention, with George Duke, Chester Thompson, Ruth Underwood, Tom Fowler and Napoleon Murphy Brock. The album itself features one of Zappa’s most complex and well-known tracks, "Inca Roads". One of Zappa’s heroes, Johnny "Guitar" Watson, guests on two tracks.
Early U.S. LP pressings of the album have a skip during Inca Roads. This error was a manufacturing defect not caught during the test pressing stage. The first round of pressings were recalled after the mistake was caught, but a significant number had already been sold. The highly complex nature of the music made it difficult to recognize the error without comparing it to the correct version.
In 1988, One Size Fits All was released on CD by Rykodisc.
