John Popper is the greatest harmonica player of all time?
Blues Traveler was a great blues band and John is one o the best harp players ever. He plays in basically the blues. Can he play a chromatic harp? I think not. Toots Thielemans harmonicist a studio, guitarist and composer has a very wide range of styles and musical knowledge. And plays the blues like a mofo, too! My vote is for Toots! .
