i.e. labels who offer all their music free to download.
Whenever I come across these I never really know what to listen to, they're so overwhelming because there's always so much music, and there's almost no quality control as it's costing them nothing (except hosting bills) to put the record out.
20jfg posted about Kania Tieffer before, who's kinda fun. (you can download her ep here: http://www.selvaelettrica.com/release_detail.php?id=16)
Most of the other stuff I've ever downloaded has been boring, stale IDM that no one else would probably ever put out.
But there must be some hidden gems out there, surely... Anyone got any good net label finds they want to share?
