"Only 20 years old, Streisand's control of her instrument is already dazzling, and her phrasing and dynamics are remarkably clever and sophisticated; she knows exactly what to do with this material, and delivers a set that nods to cabaret traditions as she puts a fresh and exciting spin on the art of nightclub singing. As polished and expert as she sounds here, there's a sincere giddiness and good humor in her more playful numbers and between-song patter, reflecting the joy of an artist just learning to make her gifts work to her advantage. Streisand's popularity outgrew the confines of a small club with impressive speed, and Live at the Bon Soir documents a very brief moment when she was just learning how to wow an audience. It clearly took very little time for that lesson to take, and this is a glorious archival find".
