On March 15th, it is the International Day Against Police Violence. The artist Laura Joos has produced an acoustic statement, which will be broadcast on Radio Blau on Saturday at 5 PM. The idea: Play this sound piece as loudly as possible. No matter where. No matter what device. From your phone speakers on the bus, from your laptop in the café, through the stereo system in your living room, or the Bluetooth speaker in the park, from the car radio. In private spaces, a maximum of 35 to 40 dB is allowed, in public spaces 45 to 55 dB. Join this collective action—for all the unheard voices.
