The Puppini Sisters are a close harmony vocal trio composed of Italian Marcella Puppini and English Kate Mullins and Emma Smith. Although the three are not related, the name was chosen in tribute to The Andrews Sisters. Puppini first studied fashion design at St. Martins School of Art, and later music at Trinity College of Music in London where she met Mullins and original member Stephanie O'Brien. The trio are backed by a three-piece band featuring Blake Wilner on guitar, Henrik Jensen on double bass and Peter Ibbetson on drums. After eight years with the group, O'Brien decided to leave and she was replaced by Emma Smith. Critic Arion Berger described them as part of "Retro's futuristic vanguard" and characterized their sound as "swing-punk". The group is associated with a burlesque revival.
