The Los Angeles Opera opens its 2024-25 season Sept. 21 with Puccini’s “Madama Butterfly” reimagined in a film studio and said Saturday it will present the company premiere of Osvaldo Golijov’s “Ainadamar" while reducing its offerings from six main-stage productions to five. Mario Gras's “Butterfly” staging, first seen at Madrid’s Teatro Real in 2017, stars Karah Son as Cio-Cio-San and Jonathan Tetelma as Pinkerton in their company debuts.
