I can't imagine you stumbled upon surf music because it was popular. Wesweek out the obscure and different, and I think it's important to recognize those that are really trying to do try something new. This category is to recognize groups that have a loose foothold from surf but jump into more challenging directions.
This category used to be called Best Way-Out Instro, but I was never comfortable with that name and realized that "Mad" rhymes with trad and rad and works well enough. Mad as in crazy, not angry.
