The Belfast four-piece released an over-praised debut two years ago, but this follow-up represents a great leap forward.
The template remains roughly the same -- instrumentals based around guitars and drums -- but now there are beautifully nuanced moments amid the exhilarating quiet-loud dynamics.
7 Billion People All Alive At Once offers sparse electric guitar notes and a languid tempo that builds into a euphoric coda with subtle strings employed underneath.
It's a post-rock composition to match the best work of the masters of the genre -- Mogwai and Godspeed You! Black Emperor.
And Lifeproof is a life-affirming wonder that melds frenzied guitars, tribal percussion and euphoric yelps.
It shares roughly the same territory as the intoxicating finale of Doves' There Goes the Fear and, over the course of its five-minute run time, it displays what an exceptional band ASIWYFA can be.
