“I was in L.A. because we go to L.A. every January or February … And I was looking at the orchestral setup here [at the L.A. Phil] and I thought, ‘Hmm, those first desk strings are really in a tight semicircle.’ They could hear each other very well. And the first two flutes and first two oboes and first two clarinets are ditto, also close in. If I were to add two vibraphones and two pianos, I’d have exactly the piece I was working on at the time, Runner … This is the ensemble that is [already] sitting there in most orchestras.”
