While his music hasn't received a huge amount of coverage here, this level of devotion from the minority hints at exactly what his material is capable of once it's unleashed upon the right audience and 'Like A River Runs' immediately sets the pace for the rest of the night. The initial onslaught of this track, combined with 'Shadow' and 'Wild Heart', does leave the middle of the set feeling a little laboured. But there's no denying that any number of these songs could be bothering the charts in the not-too-distant future. Not least American single 'Rollercoaster', which is tonight accompanied by a proposal within the enthusiastic crowd.
Towards the end of the set 'You're Still A Mystery' is perhaps extended for a little too long, but needs must when you're headlining internationally with a relatively short debut album. An early version of a new song with the refrain "I was born in the shadow. Shadow of the city", hints at where Antonoff is heading next and it's even further down the bombastic path explored by his debut album. The new lyrics might not be his most ambitious but who cares when you've got people singing along with the new material before the first play is even over?
When the band return to encore with 'I Wanna Get Better', the room erupts and Antonoff looks entirely comfortable with his role of pop frontman. There's little doubt that Jack Antonoff is on his way to world domination on several fronts. Tonight has proved that, in time, the UK will make sure Bleachers plays a huge role in that.
