Bagpipes are meant to be played on a battlefield, not in a "rock" band. On a foggy morning you're on the line with your buddies loading your musket and you hear the bagpipes and snare drum approaching in the distance. You can't see them yet, but you know that that sound means there's a few hundred crazy Scottish Motherf***ers out there with 2-foot bayonets on the ends of 5-foot muskets about to charge you, you know they also carry swords in case it gets too close for guns, and you know that those guys wake up pissed off just because that's who they are. They wear skirts and are firmly secure in their masculinity because they are good at killing people who want to make something of it. Bagpipes = Death Coming For You
I hate the Dropkick Murphys.
Also, my answer is the accordion.
