Oberholzer has been highly productive as a composer, musician, sound designer, and installation artist in recent years, releasing a slew of solo albums as well as a variety of collaboration records with artists such as Sara Oswald and Julian Sartorius. Büchi has recently debuted as a solo composer and sound artist working with electroacoustic techniques to create a »symphonic maximalism for the end of the world,« as she dubs it. Both are prolific and versatile artists with a penchant for working conceptually, however their collaboration as Musique Infinie is an improvisational and thus by design intuitive one. Their sessions start with an exchange on emotions and thoughts rather than theoretical questions or aesthetic debates. When they get to work—often for several hours—they rarely talk. They approached »Earth« the same way, improvising freely together and using only a few select samples from the film’s original score in the process.
Their open-ended approach is marked by an aesthetic ambivalence that perfectly corresponds with the movie’s own inherent contradictions. Dovzhenko approached his socio-political subject with poetic imagery and philosophical rigour, juxtaposing notions of traditionality with the depiction of modernity. Büchi and Oberholzer accordingly work with motives that at once seem anthemic and elegiac, working with sounds and musical motives that evoke a sense of familiarity in one moment before transforming into something futuristic and uncanny in the next. Their score for »Zemlya« is not to be understood as a mere interpretation of the movie, but rather a re-narration or even re-negotiation of its aesthetic and emotional qualities under their very own terms. »Earth« is an album that concisely depicts what is at the core of their musical partnership.
