You may hear the phrase “electronic music” and think of superstar dubstep DJs in funny helmets at beachside celebrity parties. Alternatively, you may think of the mercurial compositions of Karlheinz Stockhausen, the musique concrete of Pierre Henry, or the otherworldly experimentalism of François Bayle. If you’re in that latter camp of music nerd, then this post may bring you very glad tidings indeed. Ubuweb—that stalwart repository of all things 20th-century avant-garde—now hosts an extraordinary compilation: the 476-song History of Electronic/Electroacoustic Music, originally a 62 CD set. (Hear below Stockhausen’s “Kontact,” Henry’s “Astrologie,” and Bayle’s spare “Theatre d’Ombres” further down.)

Spanning the years 1937–2001, the collection should especially appeal to those with an avant-garde or musicological bent. In fact, the original uploader of this archive of experimental sound, Caio Barros, put these tracks online in 2009 while a student of composition at Brazil’s State University of São Paulo. Barros’ “initiative,” as he writes at Ubuweb, “became some sort of legend” among musicophiles in the know.
