Overview: Matthew Langenderfer, also known as Derf, performs in the second BlueDesk Concert to a massive crowd of fans. The lights go out, and he begins "Moonlight Sonata" surrounded by candles and his onlookers. After this unforgettable masterpiece, he begins "Vienna" to mass appeal of the mob. He then takes questions (and some heckling) before wrapping up with the reveal of the next Blueprint issue and the Alma Mater that could be heard from across the building.
