The endlessly invaluable UbuWeb has just launched an “Electronic Music Resources” section.
“This new section of Ubuweb is devoted to technical resources concerning the practice of electronic and experimental sound. This is a place for information about actual methods and techniques, with little writing on aesthetics alone. It takes the form of technical/historical articles, interviews, books, small-press magazines and patents.”
I can’t imagine reading much of what’s here, but in the very least it’s worth a look just to peruse the wonderful ads in the issues they’ve posted of Electronic Music Review, circa ’67-’68.
