There are few things in this world that make you feel more like a corporate lackey than sipping a free cocktail spiked with piss-colored (and flavored) energy drink at a show put on by said energy drink’s uber-branded festival that you didn’t pay for either. Ok, so maybe when it comes to the Marxist-guilt department, writing a glowing review about the aforementioned caffeine company’s spectacular music event tops one shameless night (ok, two) spent gobbling down all those freebies. But the real and honest-to-god truth is that Red Bull Music Academy is responsible for some truly killer (and sometimes truly rare) music happenings all over the world– Glenn Branca’s Symphonies, held at the Grand Lodge of Free and Accepted Masons, were no exception.
