labels
They provided London with all things techno through their shop in the nineties and now they provide a global audience with a beautifully diverse selection of music through their label. Check out their site for a taster. They also house a nice demo section showcasing largely unsigned artists whose work they have received but are unable to release.
I came across this show on resonance fm. It showcases purely online music labels. There is plenty to hear on Sijis and lots of links to other online music distributors.
literature
I originally heard this stuff on a tape leant to me by a friend. Read all about "The Curious Universe of Outsider Music" by Irwin Chusid.
