Under the Skin (OST)

Under the Skin (OST) is the most influential film score of the last fifteen years and it was written by somebody who had never scored a film.

Levi came out of Micachu and the Shapes, a band whose instruments were frequently built out of hardware-shop materials, and Glazer hired them on the strength of that rather than any orchestral credential. The approach is consistent across the record: a small string group, instructed to slide rather than to arrive, to play in the gaps between the notes, and to press the bow hard enough that the friction is part of the sound. Nothing on the album is in tune in the conventional sense, and the central effect — a swarm of strings all moving towards a pitch from slightly different directions — is what a great deal of horror scoring has sounded like ever since.

The viola material is the record's signature. Long, sliding, vibrato-heavy figures that behave like something trying to imitate a human sound and not quite managing it, which is a precise description of what the film is about.

It is a score about a body being worn

Glazer's film follows something non-human operating a woman's body in Glasgow, and Levi's score is scored to that rather than to the plot. The recurring motif is attraction: the cue most people know is a repeated, almost rhythmic figure that plays over the predation sequences and sounds like a pulse that has been assembled rather than felt. Against it, the record has two or three passages of genuine, unprotected tenderness — and those are the ones that are hardest to listen to, because the film has established what the tenderness is for.

The percussion is not percussion

What reads as drums across much of the record is bowed and struck string material, close-miked, with the attack exaggerated. Levi has described wanting the score to sound as though it was being made by someone who had seen instruments but had not been told what they were for. That is the single best description of the record's effect and it is why it does not sound like an orchestra playing horror music.

Where it is difficult

It is short, deliberately repetitive and almost entirely without development, and divorced from the film several cues are simply unpleasant textures. The record is also mastered quietly and loses a great deal on laptop speakers. And its influence has now been so thoroughly absorbed that a listener coming to it in 2026 may find it familiar rather than startling, which is a problem of success.

For the vocabulary it inherits, Threnody for the Victims of Hiroshima; for the score that took the same approach to a different instrument, Hereditary (OST); for the other great modern horror score of its decade, It Follows (OST).

The short answer: the record closes on its one unambiguous piece of beauty, and the film does the same thing to very different effect. Levi's score has two registers — the detuned, sliding, predatory string material and a small number of passages that are simply melodic — and the album's structure is to hold the melodic material back and then release it. In the film, the corresponding sequence is the ending: the woman is destroyed, snow falls, and Levi plays a cue that is warmer and more conventionally moving than anything in the preceding ninety minutes, which converts the whole thing retroactively into a tragedy rather than a predation. On record the running order varies slightly by release, so the exact final track depends on your edition, but every version of the album saves the melodic material for last. That is the resolution: the score only becomes beautiful once the thing it was describing is gone.

How were the strings recorded on Under the Skin?

By instructing the players against orthodoxy. The ensemble was asked to slide into and out of pitches rather than land on them, to play microtonally between notes, and to use enough bow pressure that the friction is audible as part of the tone. The recording leaves in the mechanical noise — bow on string, fingers on fingerboard — that a conventional score would remove, which is most of why it sounds organic rather than designed.

Who is Mica Levi?

A British composer and musician, previously of Micachu and the Shapes, who had no film-scoring experience when Glazer hired them for this. They have since scored Jackie, for which they received an Academy Award nomination, Monos, Zola and The Zone of Interest, and continue to work in a register almost nobody else in film music occupies.

What is the main theme of Under the Skin?

The cue that plays over the seduction and drowning sequences — a repeated, insistent, almost rhythmic figure built from sliding strings and exaggerated attack. It functions as a pulse and it is not quite one, and it is the piece that has been imitated most. Listeners generally know it as the predation music even without knowing the film.

Is Under the Skin (OST) listenable on its own?

Partly. Its best passages work as music and several of its cues are textures that mean considerably less without the image. It is also short and quietly mastered, so it rewards headphones and loses badly on a phone. The honest recommendation is to see the film first and then play the record, which is the opposite of how the Carpenter scores in this index work.

Why was this score so influential?

Because it demonstrated that a small ensemble playing badly on purpose could do what a large orchestra could not, and that a composer with no film background could produce the most distinctive score of a decade. The sliding, detuned, friction-heavy string sound that now signifies dread in trailers, prestige horror and television came through this record, which in turn came through Penderecki and Ligeti.

Scored against the published rubric, here is what the numbers mean.

Reality anchor 086 is high — only 10 works score higher. Almost nothing on the record holds a pitch, a metre or a key, and the ensemble is deliberately not in tune with itself.

Tone 008 is bleak — 11 works score lower. The score's warmth is withheld until its subject has been destroyed, which is a crueller structure than unrelieved coldness.

Era bias 084 reads modern — 81 works score lower. 2013, digital recording, close-miked acoustic sources and a contemporary mix that depends on fine detail being audible.

The threat at 045 is just under the midpoint, which is the right reading: the score's subject is something non-human wearing a human body, and the record sits exactly on that boundary.

Viscera 030 is low — 30 works score lower, though the bowing noise and the exaggerated attack make it more bodily than its score suggests.

Pace 024 is slow — 29 works are slower. Nothing on the record hurries and almost nothing develops.

On shocks: almost none. The record works by friction rather than by transients.
