Kurt "Kutte" Widmann (2 March 1906 – 27 November 1954) was a German bandleader and jazz musician known for his contributions to swing jazz in Berlin. Born in Berlin, Widmann began his musical career as a drummer before learning to play the accordion and trombone. By 1924, he was performing locally and in 1933, he led a quintet at the Hotel Imperator in Berlin, featuring sidemen like Hans Berry. From 1938 to 1942, he directed his own dance orchestra, which was a regular feature at the Haus Vaterland, performing swing jazz and recording under pseudonyms such as Billy Blackmoore, John Weepster, and John Webb. Despite censorship during World War II, his band continued to perform for German troops. Drafted into the Wehrmacht, Widmann was released in 1944 due to health issues and continued to play in cinema houses during the war's final days. After the war, he formed a new band for performances during the American occupation, utilizing both wartime arrangements and new contributions from arranger Walter Jenson. Widmann recorded again in the late 1940s and passed away from a stroke in 1954. His life inspired the 1955 film "Music in the Blood," directed by Erik Ode.
