I recently discovered a duo named Rodrigo y Gabriela They will be touring the US in March. Guitar World did a feature on them either this or last month. It would be incredible if GT could get an interview with them or even have a contest for tickets to their concert. The started as guitarists in Mexico underground hard rock and went to Ireland and learned Celtic music and technique. They have an amazing, unique sound,(imho) Here is a list of links to find out more about them if you don't already know. Their site has several songs you can listen to
