639 Years in a Single Chord

On Wednesday, 5 August 2026, it happened again: a chord in John Cage’s Organ2/ASLSP (As Slow as Possible) changed after two and a half years. Classic FM reports.

The work was written by the American avant-garde composer John Cage in the mid-1980s. The score consists of eight pages of music, and, as the title suggests, the instruction is to play it »as slow as possible.«

On piano, the work can last around an hour. But on organ, Cage’s idea of slowness can unfold on an entirely different timescale. In the most extreme performance, the work lasts not hours or days, but 639 years.

Since 2001, Organ2/ASLSP has been performed at St Burchardi Church in Halberstadt, Germany. A specially built organ has been installed for the project, and the performance is scheduled to continue until the year 2640.

This means that individual chords can sound for years at a time. When a change finally occurs, it therefore becomes an event in itself. The latest chord change took place on 5 August 2026 – two and a half years after the previous one.

The project began symbolically on Cage’s 89th birthday in 2001 and will continue long after all the people experiencing it today are gone. No audience member can hear the work from beginning to end. They can only arrive at a particular moment and hear the fragment of its 639-year duration that happens to unfold before them.

An Organ in the Dark Forest of Doubt

Calum Builder: »Although Changed, I Arise the Same«

Thanatosis, 25.09

Kristoffer Møllegaard

Last year, Builder released Poor_in_Spirit, an album in which he explored, on his own, the sonic possibilities of his self-built organ. It was an album shaped by this exploration, but ultimately also by the limitations of the organ itself. On Although Changed, I Arise the Same, the composer finds a way beyond them.

The organ is now joined by three additions: Builder’s own alto saxophone, along with the voices of Zola Mennenöh and Johanna Sulkunen. It makes all the difference, providing the diversity of instrumentation that Builder has repeatedly demonstrated his ability to compose for. At times, the organ’s bass sinks beneath the voices and saxophone like a light haze; at others, it envelops them in a heavy fog. It howls like wind in the trees and roars like a train in the night. Mennenöh and Sulkunen sing, chant and breathe simple, repetitive phrases about spiritual uncertainty and searching, as though lost in the dark forest of doubt.

It is a Spartan form of storytelling, giving the listener enough lyricism and atmosphere to set the mind in motion, but never so much that it becomes overwhelming. This is where Builder’s strength lies: his music clearly grows out of his life and experiences, yet he composes in such a way that the listener is invited to enter the story with their own imagination.

Builder determines the colours, but leaves part of the picture to the listener. It is an album that is far more restrained in its dramaturgy than previous releases. No less beautiful or inspiring for it.

»For us, music is a transcendent force with transformative potential – something we get to experience and shape when we create sound together. It is an opportunity to describe one’s innermost universes without words, and the best way for an introvert to express intense emotions at full volume.«

With roots in Copenhagen’s experimental jazz and punk scene, Echo, Bravo challenges the notion of what a rock band can sound like. The quintet blends post-punk, free punk, and noise rock into a raw and unpredictable soundscape. They describe the music themselves as a kind of »empty-the-fridge soup,« where various leftovers come together. »Best enjoyed as a hot meal in a cold industry.«

The Trombone Finds Its Quiet Side

Francisco Coll: »Tapias«

Stavanger Concert Hall, 17.09.26

Andrew Mellor

At 19, the Spanish composer (and trombonist) Francisco Coll wrote a wild-child of a trombone concerto that pushed the instrument out of its comfort zone. 22 years later he has created a new piece from some of that material. Its priorities are the opposite.

Tapias embraces the lyrical, ethereal qualities of the trombone. It is not a concerto, insists Coll. Perhaps it could be described as a set of frescoes for trombone and orchestra. Whatever the category, it’s a beguiling piece that was gorgeously birthed on Thursday by Ian Bousfield, conductor Nuno Coelho and a sumptuous-sounding Stavanger Symphony Orchestra.

Composers from Sibelius to Turnage have reacted against caricatures of the trombone as brusque and clowning by exploring its dark-hued lyricism. Coll does something more, setting his soloist’s introspective, intervallic melodies in evocative and provocative orchestral contexts. The soloist’s lines can resemble spray-canned tracings on walls already heavy with the patina of history, decoration and graffiti.

Initially the trombone appears to seek repose. The second movement draws it into more agility but the dancing is suppressed: a layered burying of all manner of rhythms from flamenco to Hiphop. Great wodges of rich harmony weigh the boogying down for good.

The trombone does find peace in the final movement – its long, soulful melodies more yielding. But not before Coll has conjured up moments of huge harmonic strain and conscious orchestral magnificence. They sat well next to Coelho’s fierce performance of Shostakovich’s Symphony No 5 after the interval. But Bousfield’s heartfelt journey through Tapias, sounding entirely at one with the orchestra, will linger longest in the mind.
