”All in all, All Knots Untied is an astoundingly good album that any fan of progressive black metal should enjoy. It’s one of the strongest debuts I have heard in years. I wholeheartedly endorse this album, and I strongly recommend that you give it a shot. - 5/5 Self-Destroying Toilets”

“Nixil delivers slithering melodies backed by skull-busting drum strikes and ominous fanfares of sound veering into paroxysms of blasting, unhinged riff-fever and gut-punching bass tones...” Islander, No Clean Singing

"Black metal is a crowded field, but Nixil find it easy to avoid cliché. Their music embraces a progressive soundscape that promises much and delivers more in abundance. Seldom does their art lose direction, and they’re quick to recover your attention when things threaten to die down. Nixil’s debut offering deserves thirty-six minutes of your time. - 7/10”
