Binaural production - listen with headphones for full immersion! I embarked on a dreamlike journey through Cologne when I visited the Museum Ludwig that presented collaborative works by John Cage, Merce Cunningham, Jasper Johns, Cy Twombly and Robert Rauschenberg.

Occasionally, you would also hear the gentle voice of John Cage. Afterwards, I immersed myself in the cathedral, which resonated with the sounds of its visitors.
