Produced by Streisand, Martin Erlichman, and Jay Landers, the Bon Soir tracks were remastered under the supervision of Streisand and Jochem van der Saag. "The club's acoustics were obviously not designed for recording, and there was a lot of leakage from the instruments into [Streisand's] vocal mic," said van der Saag, requiring the use of spectral editing technology to properly mix the recordings.
