Jim resonates vocal/breath gestures through wind instruments, exploring fissures between musical systems and noise. In 1997 he released a solo CD of his work with the Random Module Twins, Sonic Hieroglyphs. Warren Burt writes in Experimental Musical Instruments about this work, "a poetic vision of landscape that both refers to the ongoing engagement with landscape that has been a constant feature of Australian art for about 20,000 years". Jim feels there is no need for distinctions to be made between his roles as improviser, composer, instrumentalist and technician.
