Munich Indie is a collective of indie devs and game enthusiasts who gather regularly for game jams and various get-togethers. Spearheaded by the organizational miracle that is Alex Zacherl of the Munich based Fairytale Distiller, the monthly game jams that happened throughout 2011 and 2012 enabled us all to experiment with a lot of different technologies and concepts, and I obviously could do whatever I wanted on the audio side!
Also, there's an instance of the Global Game Jam happening every year in Munich, which also is a fantastic playground for sonic experimentation.
Munich Indie's Website has more info on the various projects and stuff we do:
