Heres some i know, and as far as i know is amongst the best there is;
- Infested Mushroom (Goa Techno)
- DJ Dean (Dance/Techno) [Play it hard/Protect your ears]
- DJ Ti?sto (Trance) [Love comes again]
- DJ Tomcraft (Trance/Techno) [Loneliness]
- DJ Zany (Hardstyle)
- Cascada (Trance/Dance)
- DJ Mangoo (Trance/Dance) [Eurodancer you must know?]
- Groove Coverage (Trance/Dance)
- Ian Van Dahl (Club/Trance) [Castles in the Sky]
- Lasgo (Trance/Dance) [I got to experience 'em live once!! :D)
- Pulsdriver (Club/Dance/Trance) [Cambodia + alot of remixes]
- Sash! (Techno/Dance) [Equador - every trance listener knows this one!?]
- Rocco (Trance/Dance) [Not THAT famous, but try "Everybody" and "Drop the Bass"]
And so forth..
These are, as far as i know some of the most known artists.
As least; Infected was, as far as i know one of the first there ever was at the Techno genre. Ti?sto has won alot of prizes and DJ Dean is one of the leading DJ's in germany etc.
But they're IMO all good.
Besides those i listen to alot of amature music where you can get free music. All though it's in danish, so you might wanna reconsider
But if you wanna give it a try, then feel free to add me on MSN - i'll hook you up with some. (I promise you won't get disappointet!:) )
