+Music has always been a significant part of my life. Since 1995, I have been mixing on turntables. I also tried composing my own songs, but they never turned out very well.
+
+## Music on Computers
+
+My first attempt at making music was on the computer. I never enjoyed live playing, so I sought a better way to create music. That's when I discovered MOD-Trackers. There are some nice MOD files, but they are very computer-based and don't sound like real music.

+
+## Live Synthesizer Music
+
+Later on, we tried to perform some live music. There are two tapes with live music that I will digitize very soon. One tape is a live recording from the <b>S.O.N.A.X meets Genital Angriff</b> session in our party room (screenshot follows), and the other is a solo tape from Genital Angriff.

+
+## Live Turntable Mixing
+
+I started mixing later in life and never aspired to be a star DJ. I really enjoyed mixing at private parties and smaller events. In the 'DJ examples' box, you can find the latest afro-cosmic-double-mix with my DJ friend <b>Marc le Nain</b>, a live recording at the <b>Private Lounge Party V</b>.
