Greg Puciato and the rest of The Dillinger Escape Plan are incredible performers. Greg puts his life on the line night after night, blowing fire, climbing onto the side of the stage and on the ceiling, the guy is an animal. Ben Weinman and Liam Wilson flail around so much I'm surprised they can still manage to any notes, let alone just about all of them. I was supposed to see them in 2005 but they had to cancel.
St. Vincent is the polar opposite, but another great performer. Whereas The Dillinger Escape Plan are an explosion of chaotic, visceral energy, St. Vincent's movements are very calculated and subtle. I'm going to see her next month.
Unfortunately I haven't seen many acts that are known for their live shows. Most of the shows I have been to have either been huge arena rock/metal bands or local groups (some of which are incredible, though). I am thinking of going to a Dropkick Murphys show in August when they're in town. The perks of music journalism.
