I am probably the biggest fan of psytrance 'round these parts... absolutely love it. it's saved my life, more than once. I live in Seattle, where I feel blessed to have such a strong psy scene.
It's unfortunate that Infected Mushroom doesn't make psy any more, because they used to be one of the best. If you've heard their new single, Cities of the Future. It's really good pop, though =P... some of my favorite artists include HuxFlux, Digital Talk, Rinkadink, Cosmosis, Hallucinogen (of course), Process, Grapes of Wrath.. oh the list goes on.. !!..
on the flip side, I'm really into SpeedBass, which is to hardcore, what hardcore is to polka. check out
www.speedbass.net . just know that the motto is "speed bass sucks" =)
also really into IDM, which actually has a very strong thread here in the Music forum, something like "Any IDM/grindcore fans?"... love L'usine, Boards of Canada, Autechre, Matmos, I Am Robot and Proud, Venetian Snares... the list goes on!..
if you want any of these or other, feel free to send me a PM and we'll figure something out. I have a few dozen gigs of music to share =)
