I like the challenge of trying different things and wondering whether it's going to work or whether I'm going to fall flat on my face.
'Hound Dog' took like twelve minutes. That's not a complicated piece of work. But the rhyme scheme was difficult. Also the metric structure of the music was not easy. 'Kansas City' was maybe eight minutes, if that. Writing the early blues was spontaneous. You can hear the energy in the work.
In a cornball way, I think being a celebrity is about making a difference, too.
