Fiedler was appointed the eighteenth conductor of the Boston Pops Orchestra in 1930. While the position of conductor of the Boston Pops both prior to and after Fiedler tended to be a phase of a conductor's career, Fiedler made it his life's work, having the position for a half-century. With Fiedler's direction, the Boston Pops reportedly made more recordings than any other orchestra in the world, most of them for RCA Victor, with total sales exceeding $50 million. His recordings began in July 1935 at Boston's Symphony Hall with RCA Victor, including a world premiere recording of Jacob Gade's "Jalousie", which eventually sold more than a million copies, and the first complete recording of "Rhapsody in Blue" by George Gershwin. In 1946, he conducted the Boston Pops in one of the first American recordings devoted to excerpts from a film score, Dmitri Tiomkin's music for the David O. Selznick Technicolor epic Duel in the Sun. RCA Victor released an album of ten-inch 78-rpm discs complete with photographs from the film.
Fiedler's June 20, 1947, recording of Gaîté Parisienne by Jacques Offenbach was eventually released by RCA as their first long-playing classical album (RCA Victor LM-1001), in 1950. He recorded the same music in 1954 in stereo and began making regular stereo recordings in 1956. A number of Fiedler's recordings were released as 45-rpm "extended play" discs, beginning in 1949, such as Tchaikovsky's Marche Slave and Ketèlbey's In a Persian Market. Besides recording light classics, Fiedler also recorded music from Broadway shows and Hollywood film scores, as well as arrangements of popular music, especially the Beatles. He and the Boston Pops occasionally recorded classical works that were favorites, but not considered as "light" as most of the pieces that he conducted. He made but a single recording with the Boston Symphony Orchestra: Dvorak's New World Symphony. There were also recordings of chamber music by his Sinfonietta. Fiedler and the Boston Pops recorded exclusively for RCA Victor until 1970, when they switched to Deutsche Grammophon for classical releases with co-owned Polydor Records for his arrangements of pop music compositions and then London Records. His last album, devoted to disco, was titled Saturday Night Fiedler.
