WATCH: Alt-J perform 'In Cold Blood' on Tonight Show

Man, I love this new Alt-J song, In Cold Blood, so much! Very excited for their new album 'Relaxer' (released June 9) along with their 4/20 Radio 104.5 Studio Session (watch live HERE).  Check out their performance on The Tonight Show with a full horn section!
