I have been doing this for a number of weeks now and if you have not already checked it out then you should.
Every Friday I hunt the realms of SoundCloud for unsigned artists that are doing great work. Like me, being unsigned and trying to get yourself heard is a hard job and getting a little bit of publicity now and then is a great thing. So via twitter I post these tracks with the genre hash tag and a #freeunsignedfriday hash tag. I do anywhere from a couple of tracks to well as many as I can fit in.

All you have to do is watch the #freeunsignedfriday hash tag on twitter and my website for all the info!

Anyway keep your eyes and ears peeled every week for unsigned brilliance!.
