The prestigious magazine The Strad wrote about the Cracow Duo: “Kalinowski and Szlezer, friends since childhood, have a wonderfully natural rapport and there is an arresting quality to their playing that gives life to the music”.
The Cracow Duo was heard in concert all across Europe and Asia, including a tour celebrating the centenary of Witold Lutosławski’s birth in 2013. In 2015 the Cracow Duo toured South Korea and the United States, performing at such prestigious venues as Seoul Arts Center in Seoul, Alfred Newman Hall in Los Angeles and Carnegie Hall in New York. Later that year, the artists performed the opening concert of their music tour in Mexico at the Instituto Nacional de Bellas Artes. Spring 2016 included their first tour in Argentina and Brazil with performances at the First Polish Music Festival at the State University in Campinas, Brazil. Their 2016 tour continued with a second visit to Mexico and concerts celebrating the 150th anniversary of the National Conservatory. They were reinvited to Brazil for the Second Polish Music Festival in Campinas. Cracow Duo visited also United States for the second time to perform an autumn 2017 tour with concerts of Polish music. In December 2017, at the Krzysztof Penderecki European Center of Music in Lusławice, they performed the world premiere of Krzysztof Meyer's "Musica concertante" with the Sinfonietta Cracovia Orchestra conducted by Jurek Dybał.
Cellist Jan Kalinowski and pianist Marek Szlezer share a special commitment and fascination with music written by lesser-known Polish composers, whose works they tirelessly perform at home and abroad. Among their many programs, the Cracow Duo frequently presented compositions for cello and piano by Aleksander Tansman, Zygmunt Stojowski, Ludomir Rożycki and Tadeusz Majerski, as well as works by contemporary Polish and foreign composers written specially for them.
In addition to concertizing, the Cracow Duo has been featured on several CD recordings: Tansman: Works for Cello and Piano; Fryderyk Chopin – The Complete Chamber Works; Baczyński (guest performance); Dedications /Kalinowski & Szlezer/; Krzysztof Penderecki: Chamber Works Vol. I; real life song (guest performance); Memories (issued on the occasion of the 15th anniversary of the ensemble's artistic activity).
