machine built by Scully. Zappa included a large number of overdubs, playing unconventional instruments through studio effects, and speeding up or slowing down recordings for artistic effect. Zappa wanted to make an album that would challenge the complacency of contemporary music fans, as he felt that his fanbase was "accustomed to accepting everything that was handed to them ... politically, musically, sociallyeverything.
