Also reminded of me of an interview with Buckethead explaining his alter ego:
""Because I was always super scared to play, and I didn't really link that together, I just thought 'This is weird.' Like a horror movie guy. And when he saw it he was like 'You should just go for it!' I was like 'That would be cool.' Because I could do everything I liked doing as this character that I'm totally scared to death to do otherwise. And it applied to all the stuff I like, like Disneyland and martial arts and dancing, all that stuff I liked. I was like, 'I can't do it just like me.' It was a great way to get all the stuff out."
