Great electronic music is done by: Nathan Fake, James Holden, actually most of the Border Community-label, Dominik Eulberg, Ricardo Villalobos, Stephan Bodzin, Tiefschwarz, Vitalic, Legowelt, some of those Ed Banger cats, T Raumschmiere, Apparat, Squarepusher, Aphex Twin, Daft Punk, and some other cats.
(not disciminating by genre)
Tiesto's crappy harmonic synth-strings pop has been lame for quite a long time now. Trust me I'm Dutch, I'm so fucking fed up with all this trance people have been listening to for the last decade. Even gabber was better than this.
