One of the great pleasures of listening to an active electronic musician for an extended period of time is observing how they bring new equipment into their orbit. There is the question of how that equipment, in turn, informs their work. There is also how they achieve their now familiar sounds with unfamiliar tools. The musician Dustmotes’ adoption of a new percussive-oriented sampler is a case in point. The London-based Dustmotes, also known as Paul Croker, has been making elegantly gritty instrumental hip-hop at least since 2011, which is the earliest credit on his discogs.com page, and also the first year I wrote about his music. His music often features a slightly drifting rhythm, a beat missed here, a tempo ebbing there. He regularly explores gentle sounds on well-circumscribed repeat against muffled beats. Playing with a new tool, the Elektron Digitakt, he recently posted a short video, which he dubbed a “Spontaneous live performance” in the brief accompanying note. It has all the modesty of his earlier work, with a newfound level of grit and glitch. The video was shot overhead, so you can watch as he goes. Even if you’re not familiar with the Digitakt’s interface, you can infer correspondences between action and sound — how a knob adds a new effect, or changes the pitch, or welcomes additional elements. It’s a great piece.
