In page Arturo Toscanini:

"

In June 1954, Toscanini participated in his final RCA Victor sessions, recording re-takes of isolated unsatisfactory passages from his NBC radio broadcasts of the Verdi operas Aida and Un Ballo in Maschera, for release on records. Toscanini was 87 years old when he finally retired. After his retirement in 1954, NBC disbanded the orchestra.[13] Most of the orchestra's membership reorganized as the Symphony of the Air,[14] The ensemble appeared in concert and made recordings until its disbandment in 1963. NBC used the "NBC Symphony Orchestra" name once more for its 1963 telecast of Gian Carlo Menotti's Christmas opera for television, Amahl and the Night Visitors.[citation needed]
