I've already previewed the Latin lineup at Shakori, which runs Thursday (10/9) through Sunday (10/12).
I'm excited to see Puerto Rican Plena Libre at the Dance Tent tonight (and again Friday night, at the Meadow Stage). Their latest CD is a live album recorded in Mexico entitled Plena al Salsero. For a taste of their sound, listen to the sample on this page.
