PORTopera’s staged concert of Giacomo Puccini’s “Tosca,” at 7:30 p.m. Thursday at Merrill Auditorium in Portland, will feature internationally renowned bass-baritone James Morris as the evil-plotting Scarpia. The cast also includes Alexandra LoBianco as Tosca, Adam Diegel as Cavaradossi, Thomas Hammons as the Sacristan and Robert Mellon as Angelotti.

Morris performed at the Metropolitan Opera this season in one of his signature roles, Hans Sachs in Wagner’s “Die Meistersinger von Nurnberg.”

“Tosca” contains some of Puccini’s most recognized arias.

The opera will be presented in a unique staged format developed by PORTopera artistic director Dona Vaughn.

As part of the performance, scenic effects are created with lighting and the music is played onstage.

The lighting designer is Tony Award-winning designer Christopher Akerlind, who lives in Portland and returns to PORTopera after designing the lights for 2012’s “La Bohème.”

The performance will be conducted by Stephen Lord, one of four conductors chosen by Opera News for its “25 most powerful names in U.S. opera.”

Tickets are available at porttix.com or in person at the Merrill Auditorium box office on Myrtle Street in Portland.
