In 1973 he formed Mandrake, a progressive rock band that incorporated elements from heavy metal and krautrock.  Being one of the few Japanese progressive rock bands of its time, Mandrake achieved little success and released no albums during its lifetime.

With Hirasawa at the forefront, the band went through various lineups and achieved some popularity in the Japanese independent music scene.
