Akkuphen is broadcasting the Mix Schools on internet. You too, you can ear them by using WinAmp. Add the following URL http://akkuphen.kicks-ass.org:8000 in WinAmp. The broadcasting is generally done every Thuesday between 21h00 and 0h00.

I advice also to listen to ETN.fm, which is for me a good radio station on the net where you can ear some good mixes of well known DJs
