A Jam Session at Victor

A Jam Session at Victor is a recording of an authentic jam session between five American jazz musicians—pianist Fats Waller, trombonist Tommy Dorsey, trumpeter Bunny Berigan, guitarist Dick McDonough and drummer George Wettling—released in the United States by Victor Records as a 78rpm 10" record in 1937. In the United Kingdom and Australia, the record was released by His Master's Voice.

The session, which took place on March 31, 1937, at Victor's New York City studios, was quickly arranged by the label's recording director Eli Oberstein when he noticed that all five musicians were in the city at once for separate reasons. It was more impromptu than the assembled pickup group had envisioned, as Oberstein neglected to choose music for the group play, so they elected on the jam standards "Honeysuckle Rose" and "Blues" as the basis for their energetic improvised performances in the Dixieland and swing idioms. The musicians did not rehearse for the jam and also forewent a written score.

Released during the rising popularity of jazz and jam sessions, A Jam Session at Victor reached number four on the pop charts and contemporary reviews acknowledged the extempore playing. The session has been described as a historic recording and collector's item, being archived by the National Museum of American History, and its tracks have been reissued multiple times. Retrospective commentators have focused on the playing of the individuals, with some considering the jam session among the best recorded work of several of its contributors.
