A list more notable for its glaring omissions than what it includes.
Let's list some of the outside.
Maryanne Amacher, Pauline Oliveros, Éliane Radigue, Clarence Barlow, Bebe and Louis Barron... I'm brain-farting so many, keep going!
Awesome shout-out.
Missing: Cabaret Voltaire, Art of Noise, Yes ..
Laurie Spiegel
It's a bit fuzzy in where the boundaries are for the category represented by the list.
