I just got a new mp3 player for Christmas, and I'm looking for new mp3s to download. Just to give you an idea, I have bands like pink floyd, king crimson, tool, dream theater, the mars volta, animal collective, battles, sigur ros, dredg, primus, porcupine tree, shpongle, infected mushroom, greatful dead, nightwish, and the doors so far. Any other recommendations?

you might like some of these bands:
ozric tentacles
gong
gentle giant
camel
caravan
wigwam
medeski, martin and wood

Ozric Tentacles, gong, gentle giant, and camel I've heard before, and are awesome, thanks for reminding me of them. I'll have to check out the rest of those as well.

i see the infected mushroom there so you like psytrance i suggest radium.
