Experimental music has been mostly unrecognised in Australia, but it is in this "underground" area that the major innovations and creative developments in music occur. Through testing perceived boundaries, breaking rules and creating new forms, the artists in this field force us to question what, in fact, music is. Written by artists who have been actively engaged in the areas they are covering, Experimental music explores the development of forms, ideas and scenes from the 1970s to the present.
