Speaking of MGMT, I saw them live a few weeks back and the kids were shocked SHOCKED by some of the stuff they played. They finished off their three singles all prior to the encore, played "Siberian Breaks" in its entirety (met with whispers of, "what is this?", "i have no idea but it sucks", and "this is so boring"), and finished off the night with a 15 minute rendition of "The Handshake" segued into "I Found a Whistle".
It was fucking incredible how many people walked out during the encore, but it was the best part of the whole damn show.
