In 2012, their song Worst Love was one the most popular tracks in electronic music. Now Robosonic released a new EP. For Feldrecord im Zirkus, the Berlin-based DJ duo collaborated with pianist and musician Laura Weider, who once made it into the Guiness Book of Wold Records by playing a 40 hour solo piano set (!) at Bar25. Back then, the guys form Robosonic taped the whole performance including the atmospherical sounds made by the pianist and the public alike. This material became the starting point for the new track, and the video also shows the legendary performance by Laura Weider. Check it out after the jump.
