Susumu Hirasawa(平沢進Hirasawa Susumu, born April 2, 1954 in Tokyo, Kantō region) is a Japanese electropop-artist. In 1972, he enrolled at Tokyo Designer Gakuin College. From 1972 to 1978, he performed in his first band Mandrake, a progressive rock group influenced by King Crimson and Yes. In 1979 he formed a techno-pop band called P-Model, along with two former members of Mandrake. They released a string of albums through the 1980s, and in 1989, Hirasawa began releasing solo work, while also continuing to work with the reactivated P-Model beginning in 1992. The P-Model project continued until 1999; in 2004 Hirasawa started a new unit known as Kaku P-Model, which is effectively a solo continuation of P-Model.
