Rehearsing for GGR Betong gig.

[youtube https://www.youtube.com/watch?v=K1y-QunzUPI&w=560&h=315] I'm setting up the new saw blade rig, because tomorrow at 20:00 we will be performing with our noise ensemble GGR Betong at ATALANTE in Gothenburg, as the official GEIGER houseband at our festival  April-fest.
