My two cents worth. Music is music and it is all in the mind of the beholder. The fact that all music influences jazz and jazz influences all music makes it universal. Me.... I just enjoy all kinds of music. Bob made a good point but his remarks about shut up and play should refer to all musicians with a chip on their shoulder not just Jazz enthusiasts.
Hey Graham Hayseed Dixie the band you refer to as bluegrassing AC/DC as well as many others including Queen, Aerosmith, Eagles, Led Zeppelin and Lynard Skynard really ROCK.
