Ted Rubright points out Amazon has an MP3 download of the David Robinson/St. Louis Symphony performance of John Adams' Harmonielehre. No equivalent CD. Note also that Rubright played percussion on the recording.
From an Amazon review:
Robertson emphasizes the "Beethoven on steroids" violence of the opening chords, jacking up the timpani part to almost ear-splitting levels. But he doesn't just dwell on the loud parts of the score.
