Since, Andrew M. McKenzie's Hafler Trio project has seen the release of numerous albums and CDs in experimental musical styles ranging from electronic, cut-up, ambient, environmental soundscape, musique concrète, electro-acoustic,[2] and audio-montage as cinema for the ears from 1982 to present, each of which use graphic design and text for contextual juxtaposition with the recordings, as well as having a diverse but concrete philosophical and sometimes quasi-religious framework to place them in.
Despite the name, The Hafler Trio is essentially the work of one man, Andrew M. McKenzie, born in Scotland in 1963 and whose family moved to Newcastle upon Tyne shortly after.
[citation needed] There have been numerous members and collaborators alongside Andrew M.

2009 saw the shutdown of the Brainwashed h3o website, the renunciation of conventional CD releases, almost all internet activity, and the exclusive concentration on methods of "complementary education" and related disciplines referenced by and developed in tandem with the work of The Hafler Trio since its inception, under the umbrella of Simply Superior.
