Toscanini made his first recordings in December 1920 with the La Scala Orchestra in the Trinity Church studio of the Victor Talking Machine Company in Camden, New Jersey and his last with the NBC Symphony Orchestra in June 1954 in Carnegie Hall. His entire catalog of commercial recordings was issued by RCA Victor, save for two single-sided recordings for Brunswick in 1926 (his first by the electrical process) with the New York Philharmonic Orchestra and a series of excellent recordings with the BBC Symphony Orchestra from 1937 to 1939 for EMI's His Master's Voice label (which was RCA Victor's European affiliate). Toscanini also recorded with the New York Philharmonic in Carnegie Hall for RCA Victor in 1929 in a series of recording sessions, concerts in 1931 and 1933, and another series of recording sessions in 1936. He made a series of long unissued recordings with the Philadelphia Orchestra for RCA Victor in Philadelphia's Academy of Music in 1941 and 1942. All of Toscanini's commercially issued RCA Victor and HMV recordings have been digitally re-mastered and released on compact disc. There are also recorded concerts with various European orchestras, especially with La Scala Orchestra and the Philharmonia Orchestra. In 2012, RCA Red Seal released a new 84 CD boxed set reissue of Toscanini's complete RCA Victor recordings and commercially issued HMV recordings with the BBC Symphony Orchestra.[30] In 2013, EMI Classics issued a 6-CD set containing Toscanini's complete HMV recordings with the BBC Symphony. Toscanini disliked recording, especially the acoustic method and for several years recorded only sporadically as a result. He was fifty-three years old when he made his first recordings in 1920 and didn't begin regular recording until 1938, after he became conductor of the NBC Symphony Orchestra at the age of seventy. As the recording process improved, so did Toscanini's negative attitude towards making records and he eventually became more interested in preserving his performances for posterity. The majority of Toscanini's recordings were made with the NBC Symphony and cover the bulk of his repertoire. These recordings document the final phase of his 68-year conducting career.
