In the wake of the fame (or notoriety) of those two founding works of the genre now called “CNN opera,” composer John Adams and director Peter Sellars went on to the heights of the opera world. Yet librettist Alice Goodman didn’t rise along with them; instead, she moved to Britain and became an Anglican priest. Thomas May catches up with her. (Notably, both Adams and Sellars, whose collaboration with Goodman ended in long-lasting acrimony, have very warm words for her here.)
