Mary Sue Twohy ‘91 had an epiphany at a smoky bar in Arlington, Virginia, in 1996. “All through my first song I could hear the clink of glasses and the voices of people talking,” Twohy says. "So I set down my guitar and sang ’Sweet Mercy’ a cappella. The crowd went nuts." When she stepped away from the mike, she realized her career as a folk musician was about to skyrocket.
