Composer's note

Dad Goes to the Mountain

Commissioned by Brussels Philharmonic, Cassandra Miller writes Dad Goes to the Mountain, a new orchestral work for her father: "In his old age, he developed vascular dementia which impacted his spacial awareness and short-term memory, but which left his personality largely intact. I feel he was somehow transfigured by the experience. This transfiguration—and lightness—are the topics of this piece.”
A deeply personal work by the Canadian-British composer, one of the most intriguing voices in contemporary music. Premiere at the Tectonics Festival on Saturday 20 June.

Dad Goes to the Mountain for orchestra (2026)

Cassandra Miller

Chapter I: Lightness
Chapter II: Arrested by the Night Sky
Chapter III: Bright Cloud Unknowing
Chapter IV: Completeness

Dad Goes to the Mountain is a single-movement composition in four chapters, for my father. My Dad was a mathematician, theoretical physicist, and expert conversationalist. He inspired his students, his children and grandchildren to feel awe at the smallest and largest mysteries of nature. In his old age, he developed vascular dementia which impacted his spatial awareness and short-term memory, but which left his personality largely intact. I experienced him in this state as someone becoming more and more himself—he could act only from his deepest instincts which were kind and gentle. When I compare photos of him at 70 and at 80, the older ones show a much lighter person. I feel he was somehow transfigured by the experience.

This transfiguration—and lightness—are the topics of this piece. It is about a general upward ascending, about forgetting (un-knowing), and about the fluidity of time. I imagine a mountain as the goal of my Dad’s transformation, as a symbol for the simplicity of spiritual awareness—and, in quite a leap, I pretend that he is greeted on the mountain by a wind band from the Andean heights of Peru. A specific recording became the basis for my composition process: “Canchis Tierra Linda” by the Banda San Martin de Sicuani (from the fantastic label El Volcán, which has recently re-released many archival tracks from rural Peru). I wrote around and through this music—as if making fanciful drawings over it on tracing paper. This musical filigree then took on its own life, growing and ageing and forgetting. Cassandra Miller

Tectonics Festival at Flagey | Brussels Philharmonic & Ictus

Tectonics is a boundary-pushing festival for new and experimental music, launched in 2012 by conductor Ilan Volkov, a true musical omnivore with an insatiable curiosity and wide-ranging taste. Since then, it has grown into one of the world’s most eclectic and highly regarded festivals for those drawn to new sounds, bold experiments, and music that ventures beyond the expected. In June 2026, the Brussels Philharmonic and Ictus bring Tectonics to Brussels for the first time, taking over Flagey for two packed and compelling days.

Tectonics Festival 2026: Maya Verlaak & Cassandra Miller ∙ 20.06.2026 ∙ Flagey

Music as social experiment - or as a reminder how to cry. On Saturday, two brand-new creations take the stage: Maya Verlaak and Cassandra Miller each composed a new work for the Brussels Philharmonic.

Maya Verlaak, in her typical fashion, tosses aside all conventions and turns – with new rules, electronics, and a classical orchestra setup – the piece into a social experiment. Cassandra Miller’s intimate and engaging compositions take as their starting point existing melodies, which she variously deconstructs, loops, magnifies and utterly transforms.
