Even before entering the foyer, everyone can play the large metallophone to their heart's content. Spare car parts, spanners and much more - it just sounds good. There are four other installations for you in the foyer: you can play the air percussion organ with flip-flops, elicit the craziest samples from the pads on the drum table, scratch and rap at the DJ table and ... and programme the wonderful composing machine mechanically and make it sound with your muscle power!
