In the 1970s, Japanese popular music, electronic music, and new-age music flourished; those genres, as well as the Yellow Magic Orchestra (a Japanese electronic band in 1978–1983), influenced Hisaishi's compositions. He developed his music from minimalist ideas and expanded toward orchestral work. Around 1975, Hisaishi presented his first public performance, spreading his name around his community. Also, from 1978, he had worked for Brass Compositions for a long time. His first album, "MKWAJU", was released in 1981, with "Information" being released a year later. His first major anime scores were "Hajime Ningen Gyatoruz" (1974) and "Robokko Beeton" (1976).
