An astounding group of virtuosos – Yo-Yo Ma on cello, Stuart Duncan on fiddle, Edgar Meyer on bass, and Chris Thile on mandolin — reunite live for the first time in nearly a decade. Joined by featured vocalist Aoife O’Donovan, the lively talents of these exceptional artists come together on stage to create a singular sound that’s part composed, part improvised, and uniquely American — music so complex to pull off that the group likens it to a goat rodeo, airplane pilots’ nickname for a situation in which many different things need to go right to avoid disaster. Gate Time: 5:30 PM
