Why do you choose to play blues on the harmonica? Because you love blues or because you love the harmonica and it seems to be heavily intertwined with blues?
So is playing blues an ability issue, "copycat" issue or one of passion for the genre? Is there a reason players don't seem to seek an original voice on their instrument? A good example of original voice is, George Brooks, watch the SPAH jam vids, he sticks out every time it's his turn to play, even when he plays 2nd position. Jason Ricci is another person with an original sound as are Little Walter, Lee Oskar and Howard Levy etc...
