The Puppini Sisters are a close harmony vocal trio composed of Italian Marcella Puppini and English Stephanie O''Brien and Kate Mullins. Although the three are not related, they chose their name 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 O''Brien and Mullins. The trio is backed by a three-piece band featuring Blake Wilner on guitar and Henrik Jensen on double bass. Critic Arion Berger described them as part of "Retro''s futuristic vanguard" and characterized their sound as "swing-punk". The group has sought to be associated with a burlesque revival.
