Selections from 100 Models of Hegikan Roku is the second in an ongoing series of archival records of the unheard music of Swedish composer, philosopher, poet, mathematician, and visual artist Catherine Christer Hennix, co-released by Blank Forms Editions and Empty Editions. It follows 2018's Selected Early Keyboard Works and coincides with Blank Forms' publication of Poësy Matters and Other Matters, a two-volume collection of Hennix's writing. Upon her return to Sweden from New York in 1971, Hennix sought to form a large ensemble inspired by her encounters with La Monte Young and recordings by the Theatre of Eternal Music. She enlisted her brother Peter Hennix, Hans Isgren, and a dozen Swedish jazz musicians she had previously worked with, naming the group and its pieces of music after the time and days of the week according to the Angus Maclise calendar (e.g. "The Pointed Time Bus"). Frustrated with the jazz musicians' inability to comprehend and play the intervals of just intonation, she pared the group down to the trio of herself, her brother, and Isgren and christened the live-electronic ensemble The Deontic Miracle. In 1976, The Deontic Miracle performed Hennix's original compositions, alongside works by La Monte Young, Terry Riley, and Terry Jennings, as part of Brouwer's Lattice at the Moderna Museet in Stockholm. With Hennix on amplified Renaissance oboe, live electronics, and sine wave generators, her brother on amplified Renaissance oboe, and Isgren on amplified sarangi, the recordings presented here of the group's first and only public concert see them channeling late period John Coltrane and the sopranino and soprano saxophone playing of La Monte Young and Terry Jennings in the Theatre of Eternal Music. With titles taken from Japanese Gagaku, "Music of Auspicious Clouds" and "Waves of the Blue Sea" are expansive drone improvisations, breathing with the pulsating lull of cicadas' organic sonic latticework. Now accessible for the first time, these recordings by what Hennix has called "the most rejected band ever formed in Sweden" continue to fill gaps of silence from a figure whose work has until recently remained flickering at the margins of some of the most enduring cultural developments of the 20th century.
