Metacritic,
Heart Under received a score of 89 out of 100 from eleven critic reviews, indicating "universal acclaim", Reviewing for the
NME, Will Richards described Heart Under as "thrillingly untraditional
noise rock" with the band having "left behind the
shoegaze tag that has followed them around since the release of their debut" and described the band as a "a truly unique gem". Poppie Platt of
The Daily Telegraph, also found Heart Under to be a departure from the group's shoegaze sound, describing it as "moody and dark, with industrial guitars and no typical choruses", in a five-star review. Max Freedman of
Paste labelled the album as "a tornado of distorted dissonance", and claimed that it "places them among the vanguard of the British Isles' ever-crowded
post-punk scene". Robin Murray, writing for
Clash, described
Heart Under as a "striking, fantastically original work that taps into animalistic emotion", whilst Siobhán Kane wrote in
The Irish Times that it "speaks to power of resilience". Writing for
The Line of Best Fit, Kyle Kohner claimed that though "the decidedly blue atmosphere of
Heart Under can be a bit one-note, albeit seldomly, it still frequently froths from lips, almost unceasingly, with the type of music you wish more post-punk revivalists, bedroom pop darlings, and even some shoegaze traditionalists would aspire to make more of". ==Track listing==
