back to New York, where my studio had a variable-speed tape recorder. Using this machine, I transposed the bee buzzes to the subdivisions of the 12-tone equal-tempered scale and rerecorded them on another tape machine. Then, using manual splicing techniques, I edited the melody for one verse. Just this part took 52 hours of splicing work. People told me that I was crazy, but I told them to listen to the result! We added an accompaniment to the melody, recreating the "Flight of the Bumblebee" played by living bees. The Happy Moog! was recorded with Harry Breuer, one of the first musicians he met when he moved to New York City. Perrey played Moog synthesizer and other keyboards, while Breuer played xylophone and other percussion. Return to Europe (1970—2006) After a decade in the United States, Perrey moved back to France in 1970, ostensibly for family reasons. He was named musical director of a ballet company, while continuing to explore therapeutic sounds to treat insomnia. That included a project that involved shooting with dolphins in the waters near Vancouver, Canada. He also wrote and recorded music for television commercials and various French cartoons, and released several albums of this music on the Montparnasse 2000 label. In 1996, after a decade of inactivity Perrey began working occasionally with electropop musician/composer David Chazam; a collection of previously unreleased collaborative works, ELA, recorded over a number of years and at various locations, was independently issued by Chazam in May 2015; it was the final album of new Perrey material released during his lifetime. In 1997 Perrey collaborated with the band Air on the tracks "Remember" (on the album Moon Safari) and "Cosmic Bird" (on the various artists compilation Source Lab 3 Y). The following year he performed at the Klinkende Munt festival in Brussels, Belgium, with David Chazam. In 1999 he composed and recorded "The Groovy Leprechauns" for a thematic compilation album At Home with the Groovebox, issued on the Beastie Boys' Grand Royal label. In 1995 the Beastie Boys had issued an album entitled The In Sound From Way Out! that was an obvious homage to Perrey and Kingsley. In 2001 Vanguard Records released a triple CD entitled The Out Sound From Way In!, which compiles four Perrey and Kingsley albums, two as a duet and solo, plus seven remixes of Perrey and Kingsley's work, including two reworkings from the Moog Indigo
