In July 2009 a field research was held by the grassbalde institute about the sound of growing grass. Its been a side act of the Culture Palace Anwanden festival.

Outside the normal cultural program two different kind of grass: Champions league lawn and Dürer lawn have been put on an alternative stage. During three days that lasted the experiment, the puplicity had the possibility  to listen to the sounds of the different growing plants by using a stethoscope and describe the sounds for the Institute.
