Sleep Dirt

Sleep Dirt is an album by Frank Zappa released in January, 1979 on his own DiscReet Records label. It reached #175 on the Billboard 200 album chart.
The album's creation was spurred by Warner Bros.' rejection of Zappa's Läther album. After demanding more albums than Zappa was contractually obliged to provide and reediting the live album Zappa in New York, a lawsuit ensued, during which, Studio Tan, Sleep Dirt and Orchestral Favorites were issued without Zappa's permission.
