This article deals with the role of racial imagination in the acceptance of Swedish jazz in Sweden in the first years of the 1950s and discusses how Swedish jazz was connected to an American jazz tradition. It is argued that in its early reception, jazz was intimately linked to African American musicians. The advent of cool jazz and the ideas of race connected to it were key in the acceptance of Swedish jazz. By analysing the racial imagination in articles in the Swedish jazz press the article concludes that the combination of the idea of cool jazz as an authentic, white style of jazz, and an American-Swedish cooperation, authenticated a performance of Swedish jazz musicians.
