Here's a link to a free streaming download of Heiner Goebbels's Eislermaterial. One of the best examples of adapting a composer to new situations. It was thru Goebbels that I discovered Hanns Eisler, when we were both young and avant garde. Now Heiner is an innovative music theatre person and gets the German equivalent of Arts Council grants! But I remember when he used to play seedy gigs and the ICA.
