Joseph’s passion for exploring solo works from C.P.E. Bach to Luciano Berio has opened and led vital international conversations about accordion equities for decades. Media critics describe his performances as “extraordinary, eloquent…moving” (Boston Globe) and “a union of poetic imagination… and profound musicianship.” (Halifax Chronicle Herald); “strong, committed… particularly memorable.” (New York Times). Joseph was the first accordionist laureate of the BBC3 Radio Auditions and recipient of the Canadian Music Centre’s Friend of Canadian Music Award 2005 in recognition of his legendary collaborations.

Joseph’s 20 concerto commissions continue to create new vocabularies in a canon ranging from minimalist to modernist, palimpsestic to post-digital. Brian Current’s Koussevitsky Foundation concerto was cited for “… Petric’s unusual insight into how to clarify and project detail as well as a superb sense of rhythmic design.” (Halifax Chronicle Herald); the CBC commissioned Koprowski concerto premiere recording with the Toronto Symphony Orchestra “..full of …emotional power, virtuoso demands, gripping, large scale. (American Record Guide). Denis Gougeon’s En Accordeon offered “..brilliant and subtle… powerful, exciting effects (Montreal La Presse); the London premiere of Gunnar Valkare’s Sveriges Reikskonzerter commission Viaggio “… astonishing bravura.” (Musical Opinion, London.)

Joseph’s explorations have been welcomed at international festivals including Huddersfield, Washington Festival, Montreal New Music, and Agora IRCAM. Petric’s passion for accordion palimpsest includes a chamber version of Schubert’s Winterreise with German tenor Christoph Prégardien and Pentaèdre presented at the Hohenems Schubertiade, the Tokyo Spring Festival, Tel Aviv Opera, Blaue Salle Brussels and the Berlin Philharmonic Festival. Petric’s performance in the complete Sequenzas for Berio’s 75th birthday tribute at Seiji Ozawa Hall, at the Boston Symphony’s Tanglewood Festival, was cited in the New York Times as “…strong, committed… particularly memorable.”
