1) Pittsburgh Opera is staging the first world premiere in its 78-year history, and it is an opera about one of the city’s legendary baseball stars. The Summer King is based on the life of Josh Gibson, who during the 1930s and ‘40s played for both of the area’s prominent Negro Leagues teams, the Homestead Grays and the Pittsburgh Crawfords. Gibson, a catcher and prodigious hitter, is now enshrined in the Baseball Hall of Fame and is rated one the game’s greatest players ever. He also had a tumultuous and ultimately tragic life: he traveled out of the country at times to play in Mexico and the Caribbean; hoped to break baseball’s color line by being invited to join a Major League team (but was not); and died young—of a stroke, at age 35—in 1947, the year Jackie Robinson broke the color line with the Brooklyn Dodgers. Portland, Maine-based composer Daniel Sonenberg, an avid baseball fan, has collaborated with librettist Daniel Nester to write The Summer King. It’s an opera of epic scope that sets out to capture the drama and discord of Gibson’s times as well as the high and low points of his star-crossed career. 8 p.m. Pre-opera talk from 7 to 7:30 p.m. Continues through May 7. Benedum Center, 237 7th St., Cultural District. (MV)
