After making significant contributions to the world of avant-garde jazz as a member of the Ornette Coleman Quartet in the 1950s and 1960s, American trumpet player Don Cherry suffered several personal setbacks that made it difficult for him to continue working in New York. In 1970, after a brief stint teaching at Dartmouth College, Don, along with his wife, artist Moki Cherry, decided to pack up and relocate to her native Sweden. After purchasing an abandoned schoolhouse in Tagarp, Don and Moki began a decade-long collaboration that merged multicultural expressions of art, music, and radical living into a synergetic model for communal creativity. Seeking an alternative to the toxic and taxing elements of the commercial jazz circuit, the couple began organizing expanded, Happening-like concerts in unconventional contexts, coining the terms “Movement Incorporated” and later, “Organic Music” to go beyond orthodox “mixed media” in elaborating their visionary confluence of global folk musics, environmental paintings and tapestries, slide and film projection, and living theater. With a combination of original 16mm film footage, Cherry family home movies, photo slides, correspondence letters, and other archival elements, Eternal Rhythm unpacks and explores both the personal and artistic relationship between Don and Moki during the years of their collaborative practice (1965-1985), as they work through the complexities of cultural exchange and in a rapidly changing global landscape.
