The Icelandic band Kaleo would seem to be much more likely than a British songwriter to meet a North Atlantic humpback. But then this lot have made the unlikely move to Austin, Texas – no whales there. Like their fellow countryman Ásgeir, Jökull Júlíusson and pals predictably tap into the northerly sounds of Sigur Rós and Bon Iver with their atmospheric falsetto vocals. But at around the 90-second mark, their sound takes a turn that is more Americana than the likes of Justin Vernon, which makes the Mosfellsbaer-Austin journey a little more comprehensible. By the way, humpbacks all sing the same tune.
