the Twig Show Last week we went to Mostly Mozart and the emphasis was on percussion. The So quartet participated in a performance of a David Lang piece for orchestra and the group. At first we saw and heard twigs twigs snapped. The part took almost as long as takes to grow them, the twigs, and then liquor bottles were tapped. At first when I saw all those bottles lined up I thought the orchestra was going to have a party. No such luck. Then it got complicated. The Music. And better?
