In 2003 Beat Frank and Stefan Röösli built marching drum sets and marching percussion for the Swiss Powerbrass. The instruments were for the first time in use at the "World Champion Chip for Marching Show Bands" in Monza. They proved to be extraordinary and are now a typical element of the Swiss Powerbrass. Due to high demand "Go2music by frank & röösli" developed innovative instruments for enthusiastic musicians at home and abroad. Headquarters and workshop were Buochs. In 2005 Frank and Röösli invented the "Big Bass Drum". The world premiere was presented with the Swiss Powerbrass in the Casineum of Lucerne. The "Big Bass Drum" was patented. Since 2011 Beat Frank continue the company "Go2music by frank" as a sole trader. The workshop is now in Ennetbürgen.
