In early 1964, the Pyramids made the Top 20 with "Penetration," the last big national instrumental surf hit, and one of the best of its ilk. The Long Beach, California group achieved some notoriety for shaving their heads just as the British Invasion was attacking American shores. Their music wasn't all that special, though, aside from the majestically sleek, haunting groove of their big smash. They disbanded after recording one album and a few non-hit singles, divided between average surf instrumentals and clunky frat-rock vocal numbers; they also appeared in the quickie beach movie Bikini Beach. ~ Richie Unterberger, Rovi
