California may be the largest state in the Union, but it's only one state nuzzling one ocean, with only so many people living near the coastline, and a small minority of them have attempted to navigate waves on a board, much less possess the fetching physique to do so in public. Obviously, then, surf music isn't for surfers. If it were, Rhino would put out a greatest-hits EP instead of a four-disc box set. Cowabunga! is all the permanent-wave stuff most people will ever need.
