Thats awesome man, you got any recommendations? Went to a big as dub/psy fest on the weekend, craaaing dub!
Getdarker.com and start downloading.
Orrr, a good place to start and see if you like things heavy, mellow, ambient or whatever is youtube. Google some artists and then search their names in youtube and you'll know soon enough.
Heavy:
Doctor P
Bar 9
16bit
Excision
Datsik
Gorestep:
16bit
Borgore
Trolley Snatcha
Mellow:
Skream
Not really into the mellow shit, so I can only come up with one name haha.
If it turns out that you like heavier stuff, get Excision's Shambhala 09 mix from his myspace. Super good.
