?Powerhouse? is a 1937 instrumental musical composition by Raymond Scott. Nowadays it is probably best known as the iconic ?assembly line? music in Warner Bros. animated cartoons. ?Powerhouse? was first recorded by the Raymond Scott Quintette (actually a sextet) in New York on February 20, 1937, and was commercially released on the Irving Mills-owned Master Records label (catalog #111) coupled with another Scott composition, ?The Toy Trumpet.? Both titles remained in Scott?s repertoire for decades, both were adapted in Warner Brothers cartoons by WB music director Carl Stalling (along with a dozen other Scott titles), and both have been recorded by numerous other artists. Stalling, who spiced his scores with ?Powerhouse? dozens of times, never created a complete version of the work; his adaptations exist as truncated quotations.
