Isao Tomita
Matsutake was grabbed by the playback of Wendy Carlos's "Switched-On Bach" using a synthesizer and a computer at the American Pavilion of Expo '70 in Osaka. In June the following year at age 19, he made his first step into professional music as an apprentice to Isao Tomita, providing him the chance of operating one of the few Moog III-P synthesizer units in Japan.
