With branding, consistency is builds equity. Once you have built your brand identity and start to get some good attention, leave it alone and let it create value for you. Consider your branding efforts as putting money into an interest generating account like a 401K. The more you put into the same account the more interest you'll get. The more interest you get the more money you'll get. Get it?
Artists and musicians who change their brand identity often don't have much success establishing a solid brand identity and have a much more difficult time getting people to remember who they are or why they should buy that brand.
