SUPER EGO A couple of years ago, Muni put out a public safety campaign that showed this gorgeous woman in giant silver headphones texting ferociously right before she stepped into the path of an oncoming train. Tagline: "Do you want Beethoven to be the last thing you hear? "

If you're unfamiliar with Bates, he uses digital and electronic instruments to bring lush, eerie dancefloor atmospherics and a leftfield backbeat to a full symphony and chorus setting. Adding Beethoven's existential and ecstatic works to the mix might start some kind of weird fire.
