At the same time Zappa gave interviews which described his legal problems with Warner and former manager Herb Cohen.

In April 1975 Zappa had a one sided demo acetate disc cut at Kendun Recorders in Burbank, California.

This unreleased disc contains "Revised Music for Guitar and Low-Budget Orchestra", a nearly 8 minute version of "200 Years Old" and "Regyptian Strut".

Instead, Zappa opted to release a new (mostly) live album Bongo Fury in October the same year.

Much of the material from these four albums was also edited by Zappa into a four-LP box set called Läther.

But Warner claimed ownership of the material and threatened legal action, preventing the release of Läther and forcing Zappa to shelve the project.

As Zappa had delivered only the tapes to Warner, Studio Tan was initially released with no musician or songwriting credits.

[8] Warner also commissioned sleeve art by cartoonist Gary Panter, which was not approved by Zappa.

Studio Tan was first released on CD in October 1991 on Zappa's Barking Pumpkin label along with the Panter artwork and added credits.
