"One Size Fits All" by Frank Zappa and The Mothers of Invention Is Released

One Size Fits All is a 1975 rock album by Frank Zappa and The Mothers of Invention.

It is the last Zappa album to be recorded with The Mothers of Invention. A special four-channel Quadraphonic version of the album was prepared and advertised, but not released.

The album features the final version 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 at approximately 4:40 into the track. 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.
