After having impulsively bought tickets for both nights in DC I wondered whether I had made the right decision. After two nights of powerful and exquisite musical performances, my only regret is not having also ponied up for Newark and Philadelphia. To these ears the 29th was slightly better and clearer-sounding. But perhaps that's a reflection of having gotten the "Fallen Angel" I was hoping for, as well as "Discipline". And that leads one back to the premise: see as many of these shows as you can manage.
