One of my personal favorites, Taiwanese shoegaze quartet TuT, have made their long-awaited demos available for download. They originally released their first demo Send Me earlier this year in Muso Planet volume 4 and have been working hard since to get some more recorded music out there. Along with Send Me they have uploaded 4 more tracks to Indievox, all of which are available for whatever you are willing to pay. All money earned will be going toward putting out a proper release.
The site is in Chinese so navigating can be a little difficult, but it is definitely worth the time to get some really wonderful music. http://www.indievox.com/tut
