One or two times every Year there is an event in Jena called “Schallspielnacht”, by PhonTon e.V..
The association is a union of musicians and band from Jena and around, which are sharing a rehearsal-house and organising events together.
I am – even though I am living in Bremen now – member of this association, have still my drum-set there and I am taking pictures of events I accomplish to visit.
