Being good at what you do is not good enough. You must avoid looking less good than the competition and there are only two ways to do that if you are not lucky: cosmetics up to plastic surgery - or simply avoiding any way to be seen as you are. See Residents, see K.I.S.S. I very much like the idea of avoiding any physical appearance of the musician on the artwork e.g. CD sleeve/cover or booklet (the same for the artwork with vinyl records, tape cassettes and downloads). Still you feed the visual channel in this or that way, or as Wazlawick puts it: It is not possible _not_to_be_communicating_ on whatever channel.
As for live performance without Residents- or K.I.S.S.-like camouflage: Keeping the lights tto low for mobile phon videos that will expose you on youtube?
