Yellow Magic Orchestra was a Japanese electronic music band formed in Tokyo in 1978 by Haruomi Hosono, Yukihiro Takahashi and Ryuichi Sakamoto. The group is considered influential and innovative in the field of popular electronic music. They were pioneers in their use of synthesizers, samplers, sequencers, drum machines, computers, and digital recording technology, and effectively anticipated the "electropop boom" of the 1980s. They are credited with playing a key role in the development of several electronic genres, including synthpop, J-pop, electro, and techno, while exploring subversive sociopolitical themes throughout their career. The three members were veterans of the music industry before coming together as YMO, and were inspired by eclectic sources, including the electronic music of Isao Tomita and Kraftwerk, Japanese traditional music, arcade games, funk music, and the disco productions of Giorgio Moroder. They released the surprise global hit "Computer Game" in 1978, reaching the UK Top 20 and selling 400,000 copies in the U.S. For their early recordings and performances, the band was often accompanied by programmer Hideki Matsutake.
