From my workshop activities at various universities, I knew Prof. Middelkamp and his work from personal experience, and it was clear to me that I would ask him to design my studio. In the end, the acoustics of my recording room not only exceeded my expectations, but were commented on as "perfect" by all of my production partners (including Humberto Gatica, mixing engineer Thriller, M.Jackson, etc...) without exception and with undisguised enthusiasm. All musicians, whether classical, jazz or pop, without exception, feel so comfortable in this room that they like to stay for many hours to make music together.
I still cannot understand how it was possible for Matthias Middelkamp to design such a room, in which I can rehearse, concertize and record with the most diverse instrumentations from solo to orchestra with perfect sound.
From the beginning, Matthias Middelkamp advocated that the appearance should also be appealing and planned accordingly. A suggestion that was to prove extremely important in this period of transition from pure audio to audio-visual production.
