Living in Montreal, the winters are so insane that in May, when it finally starts to break, there’s this really crazy feeling in the air as people kind of re-emerge from their houses, and there’s this almost kind of violent energy about it. 

And the weather gets really weird, and there’s wind storms. And like yesterday, it was like 95 degrees, and there was a hailstorm. Like, these clouds just came in, and hail came down, and the wind knocked out all the power lines, and there were power outages, and we were trying to rehearse. 

So [‘Month of May’] is just trying to get some of that feeling onto a record.
