I enjoyed The Addition of the Letter A to the symphonic experience, though I found Bates' zips and scratches far more interesting than the sweeping strings/movie music quality of the orchestral writing. Rhythm ruled, to be sure, which may have emphasized the banality of the orchestral sound. Then again, I fully appreciated Bates' nod to Satie (omnivorous furniture...furniture music) and accepted the boredom as part of that joke. With the orchestra held in check by a steady, pulsing rhythm, and with not much more than a slightly expanded percussion section (gongs, cymbals and mallet instruments) for exotic spice, Bates' electronica became immediately accessible. By contrast, hearing Varèse's musique concrète (er, electronics) is still a challenge for my ears, and wonderfully so. Mason Bates is obviously tapping into a different aesthetic (or audience) with his own integration of the orchestra and electronic music. Sorry, electronica.
