Karen Slack
Praised as “one of opera’s strongest voices at present – both as a singer and a shaper of its culture” (The
Washington Post), GRAMMY® Award-winning soprano Karen Slack is celebrated as both an extraordinary

Aristo Sham
In 2025, Aristo Sham was awarded both the Gold Medal and Audience Prize at the Van Cliburn International Piano Competition. Praised by critics as “a marvel of deft characterization”, “consistently authoritative,” and by the The New York Times as a pianist “whose playing combines clarity, elegance and abundant technique.” Sham has dazzled audiences across five continents. His performance of Brahms’s Piano Concerto No.2 in the final of the Van Cliburn was lauded for its “purpose, direction, structural awareness, technical finesse and mature artistry” by Gramophone.
In previous seasons, Sham has appeared with the London Symphony, Hong Kong Philharmonic, English Chamber, Orchestre Chambre de Lausanne, Utah Symphony, and Minnesota orchestras with conductors including Sir Simon Rattle, Marin Alsop, Edo de Waart and Sir Raymond Leppard.
