The production's originally announced star attraction, mezzo Denyce Graves, canceled a few weeks ago for health reasons. Stepping in was Kirstin Chavez, sounding like stellar material herself, with a ripe, evenly produced tone; lots of dynamic phrasing (even at rather slow tempos for her arias); and acting that, while not without its clichéd sensual poses, had a natural, involving flair. Richard Leech, as Don Jose, kept mostly to one volume, but poured on the passion persuasively. Luis Ledesma needed a little more vocal heft and tone coloring as Escamillo, but delivered the goods; he did expressive, nuanced work in his duet with Chavez in Act 4. Caitlin Lynch, as Micaela, was dressed much too Rebecca of Sunnybrook Granja, but the soprano sang radiantly, sculpting phrases with as much technical finesse as communicative richness.
