On February 28, 2020, the IYMC gathered friends and admirers of the work of Wiesław "Wild" Kaniowski, who came  to the concert "Wild is this world. For Wieśek, the musicians from Oświęcim played and sang: the band Ultrasonic and Weronika Boińska with the band. In order to support the rehabilitation and full artistic activity of the Oświęcim bluesman, a public collection was conducted during the concert. Dziki himself, together with guitarist Tadek Liszewski, returned musically with bravado after a long break due to health problems. Photo. Krzysztof Janik
