I heard early dance music on the radio, I believe it was "Open House Party" during it's early era.
But in 1993, I went to Denver, Colorado. And that did it. I owe it all to the now defunct KQKS Longmont (Denver) KS-104 (104.3 MHz). The on-air "Club 104" and "Saturday Night Techno Jam" changed my life.
I've been to raves, clubs, and listened to pirate radio, but I will never forget KS104.
