Gabe Bullard, a reporter based in Basel, Switzerland, shares his experience witnessing the 639-year-long performance of John Cage's 'Organ2/ASLSP' in Halberstadt, Germany. He uncovers the astonishingly slow pace of music that invites deep reflection, as this chord change only occurs every few years. The conversation dives into the historical significance of the Halberstadt pipe organ, unique keyboard innovations, and the philosophical implications of such a meditative project. It’s a fascinating exploration of time, sound, and art that challenges our perception of music.
