Let's put it simply. If the late 2010s come to be seen as the inception of a post-Rn’B movement, then surely Tirzah’s full-length debut will go down as one of its essential birthers.

Sparse, minimalist and exceptionally atmospheric, Devotion shares ground with very few contemporaries – only the likes of Frank Ocean’s Blonde and the late Gil Scott-Heron’s I’m New Here draw any notable stylistic comparisons. Previously known for her post-dubstep-infused, Burial-esque extended plays, on Devotion, Tirzah’s instrumentals are more delicate and patient, wallowing in lyrics that grapple with tender relationships and sincere emotions.

With production help from Mica ‘Micachu’ Levi, Tirzah’s debut doesn’t just sound like little else, but feels like it is trying to offer something entirely new. Whether it’s the singular, measured piano play on the titular track; the echoing, reverberating vocal sample on ‘Reach’ or the sunken, throbbing heartbeat of ‘Do You Know’, her beats are magnanimous and rationed. That doesn’t mean they lull or shirk to the back of the mix – they’re quietly defiant, just like her vocals.

Her personally intrusive, contemplative lyrics are confidently and emotionally delivered within her soulful, spectral range. Tirzah bares all on Devotion, and there are no bounds of just how much she can continually impress. It’s a record that invites repeated close listens, unearthing more in its lyrics and instrumentals on each occasion, and is so honest and raw that it almost feels completely original.

Tirzah certainly wouldn’t be the first artist to open up emotionally, nor the first to attempt ambitious instrumentals to accompany those feelings; but the success with which she combines these aspects deserves recognition. On Devotion, she cordons off her own corner of modern Rn’B with a statement destined to become a genre staple.
