I'm actually not an exhibitionist at all. When you get onstage and you get under the lights playing music I feel more hidden and more alone than anywhere else. You hide behind your music and let your emotions come out through the music.
I heard the Beatles and the Stones and Mom bought me an electric guitar. I played lead for four years and then switched to bass. One day someone suggested that I should sing so I sheepishly stepped up to the microphone and the rest is rock history.
