The last performance of Božidar Kunc was in the packed Ford Hall in Detroit, on April 1, 1964. The Detroit Symphony Orchestra was conducted by Sixten Ehrling and performed, with participation from Zinka, works from the international and Croatian repertoire. The focus of this benefit was the performance of Kunc's Piano Concerto in B Minor, with the composer as soloist. Immediately after the concert, Kunc had a heart attack and died.
