During the last weeks of 2025, London based alt-metal crew Night Thieves released ‘Obsidian’, a rather grandiose sounding single that blended the gothic tones of Within Temptation with the emo-ish/technical edge of early Linkin Park, creating a perfect hybrid sound that really suited Jess Moyle’s vocal style.

Their current single ‘Mycelia’ takes a rather heavier approach, whilst remaining distinctly the work of Night Thieves. The opening riffs fuse a gothic metal tone with a groove metal approach resulting in something with a genuine crunch. Throughout the verse, pneumatic drums bring more than a slight influence of metalcore, but unlike most bands associated with that subgenre, a clean vocal makes the jagged edges appear more accessible. As before, busy keys lurking beneath everything suggest a love of early Linkin Park, but unlike parts of ‘Obsidian’, this time around, the keys are used even more as a colourant.

It’s clear, just before the two minute mark, that the band are going all out for a denser approach when a slower, almost doomy riff arrives to lead into a major hook, but in true Night Thieves tradition, that hook allows Jess’s voice to soar, and despite the track’s more aggressive stance, she really maintains a great presence.

Throughout the number, the rhythm section play up a storm; Rick Hunter-Burns (bass) and Ryan Deglyn (drums) move through various mood changes and time signatures with ease, giving the complex piece a genuine flow, whilst guitarist Paul Andrew shares an impressively dirty tone throughout. With some bands, you can tell who is in the driving seat, metaphorically speaking, but this recording sounds like a genuine ensemble piece.

This isn’t as accessible as ‘Obsidian’, but in metal terms, it’s arguably far more interesting. Perfectly executed, this shows once again why Night Thieves deserve to become a much loved force on the underground metal scene.
