I come from the home-grown punk ethic, where it doesn't matter if you can't play a note, it's how you communicate.
To remove this obstacle I repeat or refer to such knowledge as has come under my notice, my own previously expressed views, and also describe and exhibit my last experiments and explain their novelty and utility.
If you want to get known as a singer you hire five sexy chicks and let them fight over you onstage and for the cameras. That's publicity, man.
