Stephen Costello is ear-candy too: here he is singing “Torna ai felici di” from Puccini’s Le villi. Care to hear him sing the whole opera? Then tune in on Sunday, January 29 to a webcast from wrti.org featuring The Academy of Vocal Arts’ production of Le villi as the second half of a double bill. The curtain-raiser, La Navarraise, will begin at 3:00 p.m., with the Puccini starting, oh, sort of 4:15-ish.
