There is something almost dogmatic about Mike Sheridan’s latest album, Touch. Everything leads back to the Cristal Baschet – a peculiar instrument from the 1950s in which sound is produced by running wet fingers over glass rods, setting metal resonators into vibration. No strings, no keys, just glass, water, skin and friction, slowly making the metal sing.

The Cristal Baschet is not merely an instrument on Touch. It is the album cover, the subject of the press photos, and almost the very argument for the album’s existence.

It recalls the material fetishism found in the American duo Matmos, whose music is often built around a single material or sound source: metal on Metallic Life Review (2025), plastic on Plastic Anniversary (2019), a washing machine on Ultimate Care II (2016). What is interesting about such constraints is that they ought to force the music somewhere it otherwise might not be able to go.

While listening to Touch, a question therefore begins to press itself forward: Which of these sounds could not have existed without a Cristal Baschet?

There are glassy tones that hang in the air and slowly change texture. Thin, cutting vibrations. Metallic surfaces that flutter, ripple, open and close. A constant sense of droning resonance; of something vibrating just on the other side of the audible.

Sheridan’s layering is meticulous. There is a precision to the mix, an almost surgical sense of the distance between the different textures. The best moments occur when the surface is disturbed: something that scratches at or short-circuits the otherwise tightly controlled resonance. On »BOW / GROUND«, for instance, deep bass pulses suddenly enter, creating a different physical quality – crackling, heavy, like something hitting the floor.

But Touch is first and foremost a well-produced ambient album. It moves through different degrees of the same state, changing nuance without ever truly changing its skin. That is not necessarily a weakness. There is something consistent, almost meditative, in Sheridan’s insistence. But the longer one remains in the same sonic state, the more one begins to miss what ought to be the Cristal Baschet’s particular possibility.

This is where the disappointment lies: in the gap between the instrument’s strangeness and the music’s conventional appearance. The sounds have been assimilated into a familiar ambient vocabulary, where the extraordinary instrument ends up producing something surprisingly familiar. You can hear that something unusual is happening at the source of the sound. But you cannot necessarily hear why it had to be this particular instrument. Had one not been told that a rare, almost otherworldly acoustic sculpture was standing in the room, one would hardly have guessed it.
