Hans Dulfer was born on 28 May 1940 in Amsterdam, Netherlands. He began at age 17 and has been referred to as "Big boy" because of his album of the same name. At the end of the sixties he and Herbert Noord (Hammond organ) founded a quartet that played saxophone/organ funk. He has performed a considerable amount of cross-over jazz and jazz fusion and has also worked with Punk rockers. He has recorded an album with saxophonist Frank Wright titled "El Saxofón". He has comparatively high popularity in Japan where "Hyperbeat" was a top-selling CD by instrumental standards. Furthermore, Japanese film maker Masaaki Yuasa stated that he listened to Hans Dulfer's music while working on Mind Game.
