The third album to be released which was made up of material originally intended for the unreleased box set LATHER, initially released in 1979. In contrast to the assortment of material on SLEEP DIRT and STUDIO TAN, this album includes some of Zappa's more ambitious pieces. Recorded live at UCLA's Royce Hall in 1975, with Michael Zearott conducting the orchestra. This all-instrumental set laid the groundwork for later explorations such as LONDON SYMPHONY ORCHESTRA and THE YELLOW SHARK.
Includes "Strictly Genteel," "Bogus Pomp" and "Duke Of Prunes."
