In Rare Sistine Chapel Concert, MacMillan’s ‘Angels Unawares’ Creates A Soundscape Of Grace
(REVIEW) Concerts in the Sistine Chapel are a rare event, which lent an immediate sense of occasion to the March appearance of renowned choral ensemble The Sixteen and chamber orchestra Britten Sinfonia.
Returning to the frescoed space for the first time since 2018, the ensemble once again paired music with spiritual gravity — this time unveiling the world premiere of Sir James MacMillan’s “Angels Unawares.”
MacMillan’s music formed the backbone of the evening. His latest work, a 70-minute oratorio, is both expansive and intimate in its overall scope. Structured in 12 movements — split evenly between Old and New Testament narratives — it explores encounters with angels that unfold with a sense of mystery rather than spectacle. The setting, beneath Michelangelo’s vast ceiling, only heightened the experience.

Under Harry Christophers’ direction, the private concert delivered when it came to sensitivity. That this concert marked the first world premiere in the Sistine Chapel only added to its significance. Yet what lingered most was not the sense that history was being made, but the work itself: A meditation on divine presence.
In a space known more for silence than sound, “Angels Unawares” felt less like an interruption and more like a natural extension of the Vatican’s enduring mystery.
“I wanted a big piece of music for the holy angels, which had never been written before," philanthropist John Studzinski, whose Genesis Foundation commissioned the composition, told The Associated Press. “When we started it, I think James was uncertain as to whether this was possible. But then when we saw the text that Robert Willis had created; James didn’t change one word, and he was so moved.”
Studzinski said, “Now we have a piece of music that can live forever,” and a piece that “really reflects some of the most emotional, powerful aspects of angels as messengers, mentors, warriors, motivators.”
One of the most striking moments comes in “The Song of Tobias,” where a traveler journeys alongside the archangel Raphael without realizing his companion’s real identity. The dawning recognition — “How could I not have known?” — echoes far beyond the text, becoming a question the audience cannot easily dismiss. MacMillan’s setting draws this realization out with patience and restraint, allowing the orchestra to hover between certainty and wonder.
Musically, “Angels Unawares” is able to balance both clarity and depth. MacMillan’s harmonic language — both modern and sacred tradition — serves the text well without overwhelming it. At the same time, the Britten Sinfonia provided a richly colored foundation, never intruding on the vocal lines yet constantly shaping the emotional landscape.
The oratorio’s central idea — drawn from Hebrews 13:2, which urges help and hospitality to strangers — grounds the work in something more immediate than abstract theology. MacMillan frames this as a call to recognize that the divine may be present in everyday life. It’s a theme that resonates beyond the explicitly religious, tapping into a broader human instinct toward meaning.
In a recent interview with The National Catholic Register, MacMillian said being a composer — especially one who is also a practicing Catholic — is “a very special vocation.”
“It is different from writing for the concert world because the responsibility of the composer writing music for the liturgy is that we are providing music which is meant to carry the thoughts and the deep prayers and devotions of the assembly to the altar of God,” he added.
In reference to his career, MacMillan, who was born and raised in Scotland, said he “wanted to be a composer from the first day [he] was given an instrument.”
“Something happened. A little switch went on, a little light went on as soon as I was given an instrument,” he added. “And the desire to write music came almost simultaneously with the desire to play or to perform music.”
