That beat. It was all about that beat. And everyone had filled up the Independent theater on February 26 to hear Four Tet's  hypnotic beats all night long. His new album, There Is Love in You, was released last month and Four Tet joined several other electronic groups last Friday on one of the closing nights of the SF Noise Pop festival. Looking like a mad scientist, tangled amongst endless cables and blinking techno-gizmo's, Four Tet honed in on some marvelous beats that made everyone on the dance floor shake their money-makers. The evening started with a three other electrifying numbers, that included Nathan Fake , New Villager , and Rainbow Arabia , who also contributed some breathtaking beats to an evening of electronically charged music.
