Harmonies sweet as sugar candy, but with a melancholy or dark twist, mark the vocals of The Cadbury Sisters, direct descendants of the chocolate giant who founded Bournville.

William Cadbury was the great great grandfather of the three sisters. He was the grandson of John Cadbury, a Quaker, who created drinking chocolate to woo people away from the demon drink. It is William's signature that is depicted on all the Cadbury chocolate bars today.

The Cadbury Sisters are hoping the sweet smell of success will also be theirs, but in the world of music, as this year they make their debut at Glastonbury Rock Festival.

As part of the girls first UK headline tour they will be stopping off in Swindon at The Vic, Victoria Road in Old Town on Thursday, May 28 from 8pm.

It is an exciting summer for the trio as they are releasing their second EP, called Sarah, in June on Fear of Fiction Records, with a launch at The Lantern in their home town of Bristol on June 17.

Jessica (vocals and percussion), Mary (vocals and electric guitar) and Lucy Cadbury (vocals and acoustic guitar) have won a number of celebrity fans including Rick Wakeman, Steve Harley and Frank Turner. They were chosen for the BBC Introducing Stage at the Radio 2 Festival In A Day at Hyde Park and have been played on BBC Radio 1 by Huw Stephens.

Their music is a sonic mix of Fleetwood Mac and Kate Bush stirred up with the more gritty Bat For Lashes and First Aid Kit.

Landlord of the Vic, Darren Simons, is delighted to welcome the all girl group. He said: "The Cadbury Sisters live in a half forgotten dream, inhabiting places we remember, yet sometimes feel uneasy about returning to. Their music is a meld of harmony, discord and mindfulness, their songs are the sonic equivalent of watching Swallows And Amazons or The Railway Children inter-spliced with The Wicker Man or Lord Of The Flies.''

The girls will be supported by George Wilding, who caught the eye of local musician Nick Harper.

Nick asked George to perform at his charity gig Avebury Rocks in 2011 for the Love, Hope and Strength Foundation. Along with Nick, he is now the only performer to have played each year since, supporting acts such as Newton Falkner and The Levellers.

Tickets to the Swindon gig which begins at 8pm are £5 in advance and £7 on the door from 01793 535713. - Flicky Harrison
