On Saturday morning, pianist Davide Martello rode up on a bike with a portable piano and played John Lennon's "Imagine" in an area near the Bataclan concert hall, where more than 100 people were killed as part of a coordinated attack at multiple sites.

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.
