Ok JohnK educate me. I'm a guy who likes my rock music but is open to new things. A few years back I had the chance to see Robert Cray which led me down the blues path. About a year ago I saw Prince. That lead me down a whole new path. In a nutshell, if it's not Country I would like to give it a go.

I don't have a clue on classical. What should a guy like me listen to as a first introduction?
