[Metzger] comes from a rock 'n' roll background. He wanted to expand himself, and Particle is a great place to do it. He brings in his songs and integrates his style, and he expands on it with his guitar.

He definitely challenged us being, when he came in, he was the most experienced out of all of us as far as touring and as far as the amount of bands he'd been in and stuff.
