aww. The caring junglist.
Tried the netlabels thread on slskboard.savagenews.com (in Electronic section)? There's some stuff in there.
Failing that, you can always pick up stuff like Grooverider's Mysteries Of Funk album off allofmp3.com (I got the entire thing at alt --preset-standard MP3, encoded on the spot by the server for me, for $2.32. The Online Encoding is free, it only costs $0.02 per megabyte if you go with the uber-high quality Online Encoding Exclusive options (where you can download the material at any quality setting in any one of the various formats offered, up to the original .wav files!)
The artists do get paid as well, the site pays the Russian Copyright and Royalties associations monies for every track purchased on there, so it's not just low-cost resale of others' intellectual property. It's not a specialist dnb site, but there's some JD&B stuff on there.
