Tossup between Streetlight Manifesto and Propagandhi.
Streetlight I've probably seen 9 or 10 times. Every single one is one of the best shows I've ever been to. Their live shows are the perfect mix of energy and technicality. They are just as precise as their studio albums, but adding the intensity of live music and a venue completely packed with people who are super into it.
Propagandhi I've only seen once, but it was fucking intense. Every song was balls-to-the-wall power. I got kicked in the teeth so fucking hard I thought I lost one, but didn't care. I was supposed to see them again last year, but the frontman got Covid the night before the show. I was supposed to see them in a couple weeks, but they canceled their American tour on account of all the Nazi shit happening here. Now I'm seriously thinking about paying an exorbitant amount of money to go see them in Canada.
