I was at the theater in Berlin yesterday watching the premiere and only performance of the play Selbstauslöser: https://askhelmut.com/events/2019-09-28-19-00-volksbuhne-am-rosa-luxemburg-platz-selbstausloser-ua
At the end of the play they got a mountain of instruments, at least 30 guitars, 20 violins a cello, trumpets, etc. and destroyed all of them within 8 minutes.
