On 27 September, we participated in the global climate strike. On Vienna's Heldenplatz, we had the privilege of sharing the stage with Austria's very own Science Busters, comedian Martin Puntigam, molecular biologist Martin Moder, and astrophysicist Florian Freistetter.

We sang three songs of the Krao Indios - songs which make you hear the Amazon - and joined the chorus in singing Martin Moder's "Ozonloch" (Ozone hole) hit. Anything between 30.000 and 80.000 people helped us headbang: Thank you all, on, behind, and especially those in front of the stage.
