EDINBURGH, Scotland (AP) — Missy Mazzoli’s desire to compose an opera about the opioids epidemic was sparked by the deaths of two cousins. “Galloping” runs through Wednesday in Scotland, moves to Sweden’s Norrlands Opera from Sept. 12-23 and the San Francisco Opera in the fall of 2027. He and Mazzoli had long contemplated an opioids opera but made progress only after commissioning a treatment in 2022 from author Karen Russell. “It wasn’t until we collaborated with Karen that we found a way in that wasn’t preachy or predictable,” Mazzoli said. “I’m really into finding that strange element that only works really for opera and some comic relief,” Vavrek said.
