Music Toronto/COSE: Joanne Yesoi Choi, Chris Au & Dior Quartet

Classical music often feels like it’s trapped behind the velvet ropes of cavernous concert halls, but the Celebration of Small Ensembles (COSE) series is shattering that barrier. On May 30, the Aperture Room—a hidden gem perched above the frantic energy of Yonge and Dundas—will host cellist Joanne Yesol Choi for what promises to be the standout performance of the series. Fresh off her recognition as the 2026 recipient of the Canada Council for the Arts Virginia Parker Prize, Choi is bringing more than just her instrument; she’s bringing a narrative.

The Artistry of Joanne Yesol Choi

To see Choi perform is to witness a musician who treats the cello as an extension of her own voice. Her work has long been defined by a rare combination of technical precision and raw, emotive storytelling. As the Virginia Parker Prize celebrates the most promising young classical artists in Canada, this performance serves as a victory lap and a look forward. Joined by long-time collaborator and pianist Chris Au, as well as her colleagues from the Dior Quartet, the program is curated to be a sonic autobiography. You won't just hear the compositions; you’ll hear the milestones that shaped them, as Choi weaves original narrated stories between pieces, bridging the gap between the performer and the audience.

A Venue with a View

The Aperture Room is, quite frankly, one of the best-kept secrets in Toronto’s event scene. Tucked away at 340 Yonge Street, this space eschews the stuffiness of traditional venues in favour of industrial-chic elegance. With its high ceilings, exposed brick, and expansive windows, it captures the afternoon light in a way that makes the music feel weightless. It’s a space that demands intimacy, which is exactly why it’s the perfect home for a COSE event. The vibe here is less 'sit still and be quiet' and more 'gather, listen, and connect.' It’s the kind of room where you can actually see the concentration on the musicians' faces, making the experience feel profoundly personal.

Making a Day of It

Being located just north of Yonge and Dundas Square puts you in the heart of the city’s most intense intersection, but the Aperture Room feels like a sanctuary above the noise. Before the concert, skip the chain restaurants and head a few blocks north to the Church-Wellesley Village for a pre-show coffee at one of the independent cafes, or wander slightly west to explore the eclectic shops near the Eaton Centre. If you’re looking for a post-show bite, the area is teeming with hidden gems. For a refined post-concert vibe, head to a nearby spot like Bar Volo for a craft beer or one of the many authentic izakayas tucked away on the side streets near Bay and Dundas.

Good to Know

This is the second installment of the three-part COSE series, and because the Aperture Room is boutique in size, these tickets will move faster than a standard concert hall seat. At $40 for a single ticket, it’s a steal for the level of talent on display, but the $100 three-ticket pass is the smartest move if you want to commit to the full series. Doors open early enough to grab a drink and settle into the space—don't rush in at the last minute; the pre-show atmosphere is half the fun. Dress code is 'Toronto smart-casual'—you’ll feel comfortable in anything from a blazer to a crisp sweater.
