Alt-J have opened up about the dark themes they explored on their upcoming fourth album ‘The Dream’.The record has so far been previewed with lead single ‘U&ME’, which is about “having a good time, togetherness, and the feeling in life that nothing could be any better than it is right now”.During a new interview with The Guardian, however, Alt-J spoke about how their forthcoming LP takes a “doomy, dramatic” turn, as the outlet described it.“We experience a lot of harrowing things in our lives,”
