Many hundreds of hours of Toscanini's rehearsals were recorded. Some of these have circulated in limited edition recordings. Many broadcast recordings with orchestras other than the NBC have also survived, including: The New York Philharmonic from 1933 to 1936, 1942, and 1945; The BBC Symphony Orchestra from 1935 to 1939; The Lucerne Festival Orchestra; and broadcasts from the Salzburg Festival in the late 1930s. Documents of Toscanini's guest appearances with the [[La Scala]] Orchestra from 1946 until 1952 include a live recording of Verdi's ''Requiem'' with the young [[Renata Tebaldi]]. Toscanini's ten NBC Symphony telecasts from 1948 until 1952 were preserved in [[kinescope]] films of the live broadcasts. These films, issued by RCA on VHS tape and laser disc and on DVD by Testament, provide unique video documentation of the passionate yet restrained podium technique for which he was well known.{{citation needed|date=March 2014}}
