Probably because of this article in the New York Times, I was moved to check out composer Nico Muhly's work. I like it quite a bit; samples below; also check out this profile in the New Yorker.

It Goes Without Saying, from the album Speaks Volumes (Bedroom Community, 2006).

A Hudson Cycle, from the same album:

A Long Line, from I Drink the Air Before Me (Bedroom Community, 2010).
