In 1937, NBC established their [[NBC Symphony Orchestra|namesake symphony orchestra]] under [[Arturo Toscanini]]. Primrose was a violist for the orchestra, but he was never their principal violist. He played with the orchestra for four years until it was rumored that Toscanini would leave the Symphony in 1941.<ref name="Dalton" />

In 1939, NBC suggested that Primrose form his own group, and the Primrose Quartet was founded. The other players (all with the NBC Orchestra at the time) were [[Oscar Shumsky]], [[Josef Gingold]] and [[Harvey Shapiro (cellist)|Harvey Shapiro]]. Primrose boasted that "no quartet ever played that had the instrumental ability of my quartet".<ref>David Blum: ''[https://books.google.com/books?id=yae7t7utvQsC&q=%22th&pg=PA96 Quintet: Five Journeys Towards Musical Fulfillment]'' (1999), p. 96</ref> The Primrose Quartet was short-lived, but recorded three sets of commercial 78s for [[RCA Records|RCA]], along with a few unissued recordings.<ref>''[https://www.musicwebinternational.com/2023/02/primrose-string-quartet-complete-rca-victor-recordings-biddulph/ Primrose Quartet: The Complete RCA Victor Recordings]'', (recorded 1940-41 in New York).
