I've been loving Rick White Archive, Venjent, and Century Media.
Rick White is one of the singers and guitarist of the first Canadian band signed to Sub Pop records, Eric's Trip. He mainly releases self recorded music, but recently he and former Eric's Trip bandmate Julie Doiron released an album, "Together" that's very good.
Venjent is a British drum & bass artist who regularly releases new tracks based on found samples.
Century Media is a German record label focusing on metal.
