Weekly jam session where everyone can participate under one condition... We listen to others and don't overprepare or show off, but instead collaborate and create music that the audience will appreciate with applause—or not... - There is a catering area where you can buy coffee, tea, water, wine, beer, or non-alcoholic beer with cash or Blik payments. - There is a smoking area; you can smoke on-site. - There is an electric piano, drums, cajon, three drums, bongos, and a bass guitar. - We have sound equipment, including an amp. It's good if you bring your own instruments, but be careful with connecting the amp so everyone can hear us. Alternatively, talk to me, Krzysiek, or the person responsible for sound. The idea is to avoid chaos and unnecessary stress.
