Colour Sound Records, a CD-R Label from New Jersey, approached as at PostEverything about the possibility of distributing them in the UK, so I've been listening to some of their recordings to get an idea of what they are like.
There is some really badly recorded (and tagged) stuff in there, but a couple of gems as well. My advize is get Firefox, install DownLoadThemAll! and snarf the lot, then decide what you like. If you like this kind of stuff at all, that is.
