Forget the coffee and the diamonds, check out the tunes!
Go check out NoiseTrade.com. Listen to an artist. If you like them, buy the album for whatever price you think is fair. Or refer three friends and get the album for free. (Or maybe it's $1. I haven't got that far yet as I'm still sampling artists and trying to see if I like any.)
A few artists have done this in the past (Radiohead, Derek Webb, Downhere) and I think it's a great idea for getting word of your stuff out there. And the potential for finding some obscure artists that you wouldn't normally hear is what intrigues me the most.
So, check the site out here.
Or stay tuned in via their blog where they explain it all and update you when they add new artists.
