Cel mai lent concert din lume continuă în Germania: aceeași piesă este interpretată de aproape 25 de ani

A performance of John Cage's "ORGAN²/ASLSP" marks a rare chord change in a 639-year concert, continuing until 2640. The project began in 2001 in Halberstadt, Germany, and features a slow interpretation of the piece. The latest change adds a note, increasing the sound to eight simultaneous tones. This event is part of a long-term reflection on time and cultural heritage, with the next chord change scheduled for 2027. The organ is maintained by an electric system, ensuring its sound for centuries to come, while tickets for the final event in 2640 are already available for future generations.
