Released on March 29, 2021, on the occasion of Piano Day 2021, for the first time on the Erased Tapes label, Graz is the new album by the German pianist-composer Nils Frahm, recorded in 2009, in Mumuth, at the University of Music and Performing Arts in Graz, Austria, and never previously released. Sometimes when you listen to a piano, you may think it is a conversation between a woman and a man. At the same time, it can suggest the shapes of the universe and describe the appearance of a black hole. You can create sounds that have no relation to anything we can measure.
