"The great Swedish tenor Jussi Björling (1911-1960) in one of his most famous live recordings and perhaps his best version of "Nessun dorma!" from Puccini's Turandot.
This comes from a benefit concert on 10 November 1944 during the "Stockholm Musicians' Festival". He was accompanied by the Swedish Radio Symphony
Orchestra conducted by Tor Mann. Björling never sang the role of Calaf on stage, but he often included the famous act 3 aria in his concert program in the early 1940s in Sweden.
