For the fourth year running, and with a slightly different line-up assembled by Kesivan Naidoo, A4 assembles the band in Basel. Taking place at Flore, the jam is 'art world adjacent' in that it coincides with Art Basel, but is free to all, no cover charge or entry fee.

The name ?!?!?! stays the same (titled by way of a happy accident when designer Ben Johnson used the symbols as a holding text while wondering what to call the event). It looks the way that cymbals on a drum kit sound.
