Day 2 of Winter Jazzfest began, for me, with Claudia Acuña at the Bitter End, reharmonizing “You Are My Sunshine” for a standing-room crowd. I feel as if I’m still digesting last night’s offerings, including a brilliantly indeterminate set by the bassist Eric Revis, the pianist Kris Davis and the drummer Andrew Cyrille; and a midnight set by Nasheet Waits’s Equality, featuring the pianist Vijay Iyer. I tumbled into bed this morning at 3:30, and spent most of the day looking forward to more of the same.
Ms. Acuña’s set, or what I heard of it, was propulsive and polished, a new-world amalgam of pop harmony and folk rhythm. The strongest creative force in the band was the guitarist Mike Moreno, who fashioned a spectacularly fluent solo over a Gary McFarland tune. But there was a general cohesion among the band that resonated clearly with the crowd.
