Hamilton doesn't do polite. I've been to enough shows in this city to know that walking into TD Coliseum on a Sunday night with Three Days Grace on the marquee isn't really a concert experience — it's a contact sport. And May 3 delivered exactly that. Before Royal Tusk had finished their opener, the room had already made its intentions clear. This crowd came to participate. I've seen Three Days Grace a handful of times over the years. Each time, something tightens. The songs get leaner, the production gets bigger, the band finds another gear you didn't know was there.
