What's all this guitar rock aboot?

Due to that curious phenomenon linguists call Canadian raising, Canadians have an accent, imperceptible to ourselves, that makes our "about" sound like "aboot." I have no idea what friends from other countries mean when they talk about this, but apparently it's for real.

This makes me wonder if Canadians have a similar condition when it comes to our guitar rock. As a nation, we're pretty deeply immersed in guitar rock, and bands that might fill a bar somewhere else fill stadiums here. Is this because we can't hear something in our guitar rock that sounds overblown and possibly comic to persons from other nations? Is there a musical version of Canadian raising? Is this why the Hip are worshiped North of the 49th parallel, between the Atlantic, Pacific and Arctic waters that insulate us from a possibly transcendental experience of minimalist playing styles?
