Steve Reich's New York Counterpoint

I got the music from Steve before I was going to record it; it said Clarinet I, and it was in three movements. I looked at it and played it a little bit but I didn’t have any idea what it was supposed to be, exactly. Funny story: I was practicing that beginning first movement in the living room and my son came downstairs and said, “Dad, you’ve got to fix the record player. It’s skipping a lot.” He thought I was playing a record that was skipping!
