Soprano Ailyn Pérez has joined the cast of “Faust” at the Lyric Opera of Chicago.

The Chicago-born soprano replaced Erin Wall, who has withdrawn from “Faust,” to undergo chemotherapy, Anthony Freud, Lyric’s general director, president & CEO, announced today.

In a press release, Freud added that “her doctors expect a full recovery within a few months, according to her manager. Everyone at Lyric wishes Erin all the best and looks forward to welcoming her back in future seasons.”

Freud continued about the inclusion of Pérez, “Ailyn made a wonderful debut at Lyric in last season’s celebrating Plácido concert, and we are delighted that she is able to join us for ‘Faust’ when rehearsals begin in February.”

Pérez noted, “It’s such a joy for me to return to Lyric Opera of Chicago for my operatic house debut as Marguerite. I’m honored to be singing this extraordinary and complex role with a dream cast of wonderful colleagues in this new production, directed by Kevin Newbury. As a proud Chicago native it will be such a pleasure to perform Gounod’s mesmerizing score in front of a home crowd, and I also look forward to working with Maestro Villaume again this season, following our collaboration on ‘Thaïs’ at the Metropolitan Opera.”

Pérez will sing six performances March 3 – 18, with soprano Ana María Martínez singing the final performance as scheduled on March 21. Benjamin Bernheim makes his house debut in the title role while Christian Van Horn sings Méphistophélès.
