The material on this album originally was intended to be part of a four-record set called Läther
, prepared for release in 1977. Then Frank Zappa
got into a disagreement with his record company, Warner Bros., and Läther
was split up into several different releases as part of a contractual agreement. The results were dumped on the market during 1978 and 1979, while Zappa
moved on to his own record label. Sleep Dirt
consists of miscellaneous tracks recorded between 1974 and 1976, including "Flambay," "Spider Of Destiny," and "Time Is Money," songs that apparently were part of an unissued Zappa
musical/rock opera from 1972 called Hunchentoot. They are sung by soprano Thana Harris
. It's impossible to say what the entire work would have been like, but this album is little more than musical fragments.
