ISSUE presents a performance of Christian Wolff’s Edges or Exercises featuring Nate Wooley (trumpet), Christian Wolff (small percussion and melodica), Michael Pisaro (electric guitar) and Kristin Nordeval (voice). In the liner notes for Wolff’s 10 Exercises, the American composer Frederic Rzewski describes the work as “not reproducing familiar forms, but revealing, behind these, life’s unpredictability. You could say it is political; improvisatory; concerned with collaborative, non-hierarchical forms of social organization; but you can’t really say what it is like (although John Cage came close when he said, after a performance of the Exercises in New York, that it was like the classical music of an unknown civilization).”
