just 3? umm well okay... for the moment I guess..

1.Genghis Tron - Technical math/grind metal, with the fusion of electronics, in a totally non-corny way, their album Board Up The House is amazing, and got voted album of the year in a couple respected music mags

2. Boards of Canada - downtempo electronic

3. Jesu - like shoegaze, but slightly heavier, just slightly, it's still pretty chill mellow stuff, just heavier chords

and Aesop Rock is great some quality underground hip-hop... Saw him live outdoors over the summer at the Soundset '08 fest in Minneapolis, great show.
