It's really hard to be 'discovered' in the music industry, I know quite a few bands who have turned to the Internet to help them. A lot of unsigned bands do go for Myspace.com but recently I have heard about Electronica Bands so I went on the site to check it out.
It has been put together really well. If yo are an independent Artist wanting to be discovered then i would defiantly look into this. My close friends who are in a band have recently signed up to this site and they are getting a lot of positive feedback.
The best thing about this is you don't have to be in a band to go online. I go on unsigned.com all the time to listen to new talent that's out there. After all without listeners to rate the site the site will not exist!
