In January, the German musician played for two hours in the Place de la Republique in Paris as a healing gesture for the city after the deadly attacks on satirical magazine Charlie Hebdo and a kosher supermarket. Martello also played through the night in Turkey's Taksim Square in 2013 amidst widespread protests and turmoil in the country.
