The Puppini Sisters are an English close harmony vocal trio composed of Italian-born singer Marcella Puppini and English singers 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 Saint Martins School of Art, and later music at Trinity College of Music in London where she met Mullins and original member Rosanna Schura, who was later replaced by Stephanie O'Brien. After eight years with the group, O'Brien was replaced by Emma Smith. The trio are backed by a three-piece band featuring Blake Wilner on guitar, Henrik Jensen on double bass and Peter Ibbetson on drums. Critic Arion Berger described them as part of "Retro's futuristic vanguard" and characterised their sound as "swing-punk"
