who he described as his "hero" and stated that "Asian music heavily influenced Debussy, and Debussy heavily influenced me. So, the music goes around the world and comes full circle." In 1975, Sakamoto collaborated with percussionist Tsuchitori Toshiyuki to release Disappointment-Hateruma. After working as a session musician with Haruomi Hosono and Yukihiro Takahashi in 1977, the trio formed the internationally successful electronic music band Yellow Magic Orchestra (YMO) in 1978. Known for their seminal influence on electronic music, the group helped pioneer electronic genres such as electropop/technopop, synthpop, cyberpunk music, ambient house, and electronica. The group's work has had a lasting influence across genres, ranging from hip hop and techno to acid house and general melodic music. Sakamoto was the songwriter and composer for a number of the band's hit songs—including "Yellow Magic (Tong Poo)" (1978), "Technopolis" (1979), "Nice Age" (1980), "Ongaku" (1983) and "You've Got to Help Yourself" (1983)—while playing keyboards for many of their other songs, including international hits such as "Computer Game/Firecracker" (1978) and "Rydeen" (1979). He also sang on several songs, such as "Kimi ni Mune Kyun" (1983). Sakamoto's composition "Technopolis" (1979) was credited as a contribution to the development of techno music, while the internationally successful "Behind the Mask" (1978)—a synthpop song in which he sang vocals through a vocoder—was later covered by a number of international artists, including Michael Jackson and Eric Clapton. Sakamoto released his first solo album Thousand Knives of Ryūichi Sakamoto in mid-1978 with the help of Hideki Matsutake—Hosono also contributed to the song "Thousand Knives". The album experimented with different styles, such as "Thousand Knives" and "The End of Asia"—in which electronic music was fused with traditional Japanese music—while "Grasshoppers" is a more minimalistic piano song. The album was recorded from April to July 1978 with a variety of electronic musical instruments, including various synthesizers, such as the KORG PS-3100, a polyphonic synthesizer; the Oberheim Eight-Voice; the Moog III-C; the Polymoog, the Minimoog; the Micromoog; the Korg VC-10, which is a vocoder; the KORG SQ-10, which is an analog sequencer; the Syn-Drums, an electronic drum kit; and the microprocessor-based Roland MC-8 Microcomposer, which is a music sequencer that was programmed by Matsutake and played by Sakamoto. A version of the song "Thousand Knives" was released on the Yellow Magic Orchestra's 1981 album BGM. This version was one of the earliest uses of the Roland TR-808 drum machine, for YMO's live
