“My life in opera has been very nonstandard,” admits bass-baritone Davóne Tines in attempting to describe a unique and groundbreaking career. In his credits, there are leading roles in world premieres such as Matthew Aucoin’s Crossing, John Adams’s Girls of the Golden West, and Terence Blanchard’s Fire Shut Up In My Bones, as well as collaborations with director Peter Sellars, and then there’s a series of pioneering works-in-progress that Tines himself is helping bring into being.
