It all started with an obsession by memory champion, author and entrepeneur Ed Cooke. Ed's obsession was an invention by the avant-garde composer Karlheinz Stockhausen, conceived and built with the help of Fritz Bornemann for the 1970 Osaka world Expo; the Kugelauditorium, Ed couldn't shake the image of Stockhausen's incredible spherical concert hall for sound and light. It was hard to find out much about Kugelauditorium, and it appeared to have been swallowed up by history, lost to the mists of time. It was such an amazing laboratory of the senses, and such an obviously pioneering feat of engineering and yet, there was nothing like it in this world, and no one seemed to care, or even know about it. In 2021, Ed and I crossed paths, and we hit the ground running trying to understand the Kugelauditorium's history and potential. We started building fast and furious iterations, small and low cost, with each version adding more complexity; incremental evolutions to deepen our knowledge of what might be possible with a spherical sensory laboratory such as pioneered by Stockhausen. We started at a fraction of the scale of the original Kugelauditorium, focusing on sound first, and experimenting with a wide spectrum of sound design, interfaces, live and recorded material, and various spatial audio formats. This is how it all began,..and the project has come a long way in a very short time with the help of an ever-growing collective of artists, engineers and architects.
