1972 and 1976. The tracks utilize a constantly changing cast of backing musicians. Most of the songs on Läther are linked together with bits of musical sound effects (musique concrète) and comic dialog from Zappa band members, Terry Bozzio, Patrick O'Hearn, and Davey Moire. More of these same bits, or "grouts" as Zappa allegedly called them, appear on other albums such as Sheik Yerbouti. Basic tracks for Lemme Take You to the Beach were recorded during 1969 sessions for Hot Rats. The track was finished in 1976 at the Record Plant in Los Angeles. Down in De Dew comes from November 1972 sessions in New York and Los Angeles. For The Young Sophisticate is a 1973 studio recording from Bolic Sound and is different from the later live version on Tinsel Town Rebellion. The album's opener Re-Gyptian Strut comes from December 1974 sessions at Caribou Ranch in Colorado. Flambe''' and Spider of Destiny were also recorded at the ranch with additional overdubs in 1976 at the Los Angeles Record Plant. These three are among the songs written by Zappa in 1972 for a stage musical called Hunchentoot. A full script exists, but the recordings of this project were never completed. The most substantial work is The Adventures of Greggery Peccary, a story set to music, which lasts over 20 minutes. The piece is scored for a large orchestra and was recorded in Los Angeles between 1972 and 1974. More orchestral works come from a September 1975 session with the 37-piece Abnuceals Emuukha Electric Symphony Orchestra, which was recorded at Royce Hall with conductor Michael Zearott. Zappa said the 1975 orchestral sessions alone cost him about $200,000. Most of the live tracks were recorded in December 1976 at the Palladium in New York City. The last recordings are live tracks including Tryin' to Grow a Chin from a February 1977 London show at the Hammersmith Odeon. This song also appeared in a different later recording on Sheik Yerbouti. History 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", "200 Years Old" and "Regyptian Strut". Zappa's liner notes in the June 1975 album One Size Fits All mention a planned studio follow up album which never appeared. Instead, Zappa released the (mostly) live album Bongo Fury in October 1975. Bongo Fury contained a
