"Surf" is a very limited term. Some of us use "instro" for that reason, and some don't worry about words. While I love the sunny 60's surf sound as much as anybody, I think instro music is kept alive and interesting thanks in part to the people that aren't afraid to leave it behind. This category is dedicated to surf's weirdo grandchildren. If you'd argue that these aren't surf at all, that's OK by me.
