"Presomnia" opens with "Intro" a brief instrumental decorated with drone effects, circular guitar motifs and tribal tinted percussion that then gradually fades away and then swells into existence again as the intro for its following track "Scowl". "Scowl" is a superb indication of how far MuN have progressed since their last release, not only as musicians but also as songwriters/arrangers, the song containing all the elements toyed and experimented with on the bands previous releases but adding to that mix a grittier, harsher edge that, although wasn't exactly missing from "Axis Mundi" and "Opia", is here ramped up to the nth degree. This "ramping up" in both musicality and intensity runs throughout the seven songs that make up "Presomnia" and when combined with the wider spectrum of vocal tones employed makes for a far more immersive and satisfying listening experience. This is especially evident on songs like "Arthur" and "Verity" where the grooves regularly transition between gentle post-rock ambience and crunching brutality and the vocals can shift from melodic growls to harsh feral roars in an instant. The band are also not afraid to get a little relentless either as the ferocious "Deceit" will attest to, a song that does not only pin you to the wall with its savage onslaught it pushes you through it! The album finishes with an epic in the shape of "Decree" a song that takes all the elements visited and experimented with on the albums previous songs and wraps them all together in one song, complex chord structures, bone-shaking bass motifs and intricate rhythmic patterns coupling with hushed vocal crooning, monastic chants and guttural growls to create something that is truly quite breathtaking and utterly mind-blowing.
