If you want to bring up classical guitarists- David Russell, Roland Dyens, Ana Vidovic, Manuel Barrueco, Scott Tenant, Jorge Morel, Kaz. Yamashita and Fred Hand all deserve to be there. Many others including Martha Masters, Antonio Lopez, and Frederic Zigante at least deserve to be considered.
As for popular guitarists they missed- Phil Keaggy, Prince (shut up Raed!!!!)
