Working on a new show to be introduced on SUPERBOOTH, Caspar Brötzmann is introducing the world of guitars to the festival program during BeSOOPER in 2022 with a first strings based live set at 8pm before the SOOPERgrail will open next morning. All „grail“-exhibitors will be welcome here as well as all SuperBooth guests to hopefully open their minds for new horizonts in between voltage and strings.
