To mark the 70th anniversary of Placido Domingo’s birth (January 21, 1941), here are eleven photographs of the great artist taken by Robert Cahen. There is little to say about Domingo’s career that isn’t self evident. He’s had more roles than Parker House. He’s a tenor; he’s a baritone; he’s a conductor; he’s an administrator. He’s a phenomenon. There’s never been a career in opera approaching his.
