Hey folks... Little known factoid about me: I love electronic music (techno, industrial, house, acid, etc.). Just ran across this incredible shockwave interactive presentation on the history of electronic music.
It features 5.5 hours of mp3 samples of electronic music, and about 100 genres. It is really a great piece of work.
Disclaimer: This site does use quite a bit of profanity. So if you are one of my youth or parents from Church checking this out, you are warned. Look at it this way: you get to hear the good, bad, AND ugly of postmodern music over the last 30 years. Enjoy...
