I've been hearing about them for a few years now, but until recently I had only listened to their hardcore ep. I finally gave their first full album a chance and was blown away. It's the elusive "emo but with happy lyrics" that I'm always looking for. And, their sound is so compelling and incredibly full for a 2 piece band.
This band is incredibly consistent. I love how the guitar work is so heavy because the singer basically learned guitar from a metalhead (at least I think that is the reason he gave).
