It's the cutting edge of disc-less music production! I've signed on with discrevolt.com (http://www.discrevolt.com) and have download cards for sale at my live performances.
What ARE these things? The size and shape of a credit card, each card has a unique serial number on it with which you are entitled to 15 downloads from the website. You are able to download 15 of my tunes (so far I've uploaded samples from each of my recordings) PLUS, you have access to the "featured songs" that all the artists on the website make available for all users.
Stop by discrevolt and check out the website and look for my page. (Steve Eulberg). I'm selling the cards for the introductory price of $12.00.
