Bridge & Wolak

Bridge & Wolak are a globe-trotting musical duo from Canada who create life-affirming concerts full of beauty, virtuosity and humour.

Michael Bridge, accordion, and Kornel Wolak, clarinet (both also play piano), met over a decade ago and immediately established an artistic alliance based on the attraction of opposites: Wolak - intensely focussed with a world view infused with sardonic humour; Bridge- flexible and fearless with a playful wit.

What they have in common is a love of classical, jazz and world music, a fascination with fusing genres and a passion for performance. They play dozens of original shows every year, exploring everything from Bach to Benny Goodman and figure they’ve logged about 350,000 kilometres on the road - from Kraków to Quito, from Nancy, France to Fargo, ND - about the same distance as a trip to the moon.
