My dad had a sound teacher who studied under Stockhausen and who actually played in the Scratch Orchestra (he went on a few rants about Cardew's Maoist turn apparently). Also he (my dad I mean) had a copy of
Treatise (I mean the
graphical score) which I looked for a while back but couldn't find. Hope it's not lost. That score is pretty much how I imagine electronic music in my mind.
*in case Apple Music comes up blank for you: Treatise, plus Feldman, New York School, Stockhausen etc (those attributed to
Eberhard Blum) ... I used to hear that stuff at home growing up.
