Textuality Unbound

                       The year is 
             1982. The sound 
               of a lone 
                          saxophone 
           drifts over the 
                 boardwalk at 
      Coney Island. S/he
                      is playing a piece
                           by Bach, plays it
                         another nine 
                                  times, sticking
                       strictly to the score 
                                  but interpreting
                       it differently 
                   each time. Is
                            s/he playing the 
                              same piece over & 
                 over or composing 
                       anew? The tigers 
                                    that observe it 
                            are nonchalant. Who 
                        is the author?
