Bay Area Supergroup The Acme House Band welcomes guest artists from France Mathieu Werchowski (violin) and David Chiesa (contrabass) for another incarnation of Grosse Abfahrt, or the Art of Gigantic International Improvisations Carried Out With Extreme Sensitivity. The Acme House Band is: Gino Robair, Kyle Bruckmann, Theresa Wong, Matt Ingalls, John Shiurba, Tim Perkis, and Tom Djll. In German, the name Grosse Abfahrt means 'great departure'. The project is to take a core group of Bay Area musicians and put them together with out of town guests, usually Europeans. Always free improvisation. This concert marks the fourth iteration of the project. The music strives toward long structures, charged silences, and extreme attention to detail.
