The stage was in three parts down the long axis of the floor, effectively dividing the Olympiahalle into two equal halves. The round center portion rotated during parts of the show, while the two end stages were used for solos and, on the right side, the piano.
The round lighted balls in the air seen in some shots, are actual drones being flown remotely around the hall.
The projected graphics are on scrim panels lowered from time to time from the overhead grid. I have seem many, many shows over the years and this one was in the top three for sure, and maybe the best from a stage show standpoint.
