From 5 to 7 September 2025, I was invited to be a member of the jury for the John Cage Award competition in Halberstadt (Germany), organised by the John-Cage-Orgel-Stiftung Halberstadt, which is in charge of the Organ2/ASLSP project, a piece for organ by John Cage that designed to last 639 years and is played continuously, 24 hours a day in the Burchardi Church.

I took advantage of this wonderful opportunity to record this work at 20 different listening points for 7 minutes each.

I then used random operations with Andrew Culver's TIC and IC softwares (available on the anarchicharmony.org website) to determine sthe order of these listening points, their respective durations, the duration and the shapes of the cross-fades between these segments.

The organ pipes present in this period are: c‘ (16‘), des‘(16‘), d‘, dis‘, e‘, ais‘, e‘‘

Recorded with a pair of Sennheiser MKH8020 and a Zoom F3.
