Thanks everyone! I used a Canon 5D Mark II with a 24-105 L lens. I keep saying that I'm going to invest in a better concert lens but I haven't pulled the trigger yet. Luckily the full frame of the 5D lets me get descent shots with ISO 1600-2000. And yes, I got to meet Jake. After the show, he went into the lobby to sign autographs. He's a very pleasant person.
