There were almost 20 different performances at the Ecstatic Music Festival Marathon concert. Of the 7 best things I saw, Nico Muly's Keep in Touch was #6 and really helped me to better understand why he is so absurdly relatively famous right now. [He's no Black Eyed Peas, but he's been featured in the New Yorker (but not by Alex Ross).]
Muhly was joined on stage by his longtime collaborator Nadia Sirota on viola and Icelander Valgeir Sigurðsson contributing a subtle but effective extra layer of electronics. The piece starts slow and meanders a bit before it builds steam. Even as it attempts to climax, it takes a few surprising detours, like it's trying to say a few contradictory things at the same time.
