IT'S hard to define a band whose fans range from Cyndi Lauper to Prince Charles.

When the performers have a background in punk, heavy metal and classical music, it doesn't get any easier.

Perhaps its best to simply buy a ticket for the Puppini Sisters and let the music reveal exactly what this award-winning group is all about.

Back in 2004, when Marcella Puppini created a new Sisters group with Kate Mullins and original member Rosanna Schura (later replaced by Stephanie O’Brien), the idea was not to try and copy the charm of a historical songbook.

Instead, the aim was to create an individual sound, which would encapsulate the trio’s eclectic influences.

The three met in the same Music College, but their résumés were very different: Kate (the blonde) had sung in the heavy metal band Killed In Action; Marcella (the brunette) had recorded the dance hit Revolution after serving time in a punk group; as for Rosanna, and later Stephanie, they both came from a classical background.

Their gigs quickly became a unique rendezvous for a mix of impassioned fans: jazz-goers, retro-aesthetes, people into nostalgia, others with a style obsession, and also kids, spellbound by the vivacity and colour which sparkled in the Sisters’ voices.

Every style was filtered through their rigorous, sunny, vocal discipline. There was no improvisation, just the extraordinary power of a wall of voices whose architecture seemed designed by a virtuoso.

In the eight years since their inception, the Puppini Sisters have received accolades from fans as disparate as Prince Charles and Cyndi Lauper, have been awarded Gold and Multi-Platinum discs and performed on iconic stages all over the world.

In Septamber 2012, the trio acquired a new redhead, Emma Smith.Emma comes from a London Jazz dynasty, and is a Royal Academy of Music graduate with a soulful voice and a very cheeky personality.

And with a change of line up comes a new direction in music, which sees the Sisters exploring their passion for mixing the old with the new, the swing with the “bang”, as they write for a new album.

We’ve been thinking about it for years,” says Marcella.

"We love antiquing rock and pop songs with our arrangements, but we also really love writing in a style that combines swing and pop in a more modern sense."
