Where are tommorrow's musicians?

Tom Brokaw named the men and women of the WWII era the "Greatest Generation" because of thier morals, dedication, and character. Watching the Elton John concert Wednesday I realize they also produced a generation of great performers.

Looking at today's music "stars", where are the musicians? Sure Brittany Spears is great to look at, and "Opps I did it again" has a good beat. But Brittany, Beyonce, Christina, and other just can't match the musical genius of Elton John, Billy Joel, and Ray Charles.

And then where are the great bands of the future? The Rolling Stones, KISS, Areosmith will there be anyone to follow up on this generation of muscians?
