The fourth solo album from Jon Hopkins (who, since 2009's Insides, has collaborated with Brian Eno and scored the British sci-fi hit Monsters) lasts exactly an hour but feels much longer. This isn't a criticism: in eight vivid, atmospheric tracks, Immunity captures the feel of an epic night out. It begins, on We Disappear, with mounting excitement that tips over, on Collider, into anxiety. The daybreak chill of Abandon Window gradually melts away into a long, blissful coda – you can feel the sun rising in the final third. Hopkins's beats shuffle and trip but there is a great clarity of focus throughout, and a delicate beauty.
