It's possible that, right now, The Arcade Fire is simply the biggest thing going.
They did a four-night stint at the Judson Memorial Church in New York City, and there are some really high quality bootlegs of two of the concerts that are COMPLETELY worth your while.
The coolest part of it, for me: They end the Feb. 16 show by singing "Wake Up" (my favorite AF song) in the crowd. They literally circled the church, came in the front doors and sang a stripped down version WITH the audience. I defy you not to get goosebumps.
So, what do they do the next night? They start it the same way. Video here.
