The singer/songwriters on Acoustic Pie Radio
This is a list of all of the artists who have played on Acoustic Pie Radio prior to May 2013. Buying directly from an artist at a live show is always best for them! But, if not, CD Baby will give Acoustic Pie a little commission if you buy by clicking on their links from this or any Acoustic Pie page. I'm also a big fan of eMusic.com. It's easiest to subscribe to a monthly plan to purchase MP3s from them.
This list is no longer maintained after May 2013. I think most people are good enough Googlers nowadays to find artist information without my help!
