Yo La Tengo at Battery Park:
Listening to music stretched on a blanket on a beautiful day with plenty of snacks sure beats standing for hours in the S and M discomfort routine of a rock club, but alas, speaker cabinets need wood to bounce sounds off of. They do not sound good outdoors. Over-zealous park organizers turned people away when the lawn wasn't even full, so we didn't get to hang out w/ Ange or Jordan.
In this setting, with trees and sunlight, Yo La Tengo did best in their quiet, casual, open song mode -- esp. w/ the breathing room created by brushes on the drums: intimate, relaxed, and operating within a carefully selected spectrum of shyness with anxiety as a back-story to give it some depth.
