That's an odd combination. I personally don't see much redeeming value in Fucked Up. I wouldn't spend money to have a shirtless fat dude yell at me for 1/2 hour.
I don't really think it is. They both developed as bands in the same area (maybe scene) and even though the music's different, I think they'd attract the same fans. But sometimes when I listen to Fucked Up, it sounds a bit like Arcade Fire without, obviously, the same singer.
