The type of band that I have now, the type of music that we're playing you either like it or you dislike it. If you dislike it, you probably don't know why. By the same token, you can't even really say why you like it.
I start with actors that I know personally or I know their work, and there are things about their work or their presence or their own personality that make a character, that exaggerates some qualities and suppresses other qualities. It's always a real collaboration for me.
