The last train to dance central is about to leave the station, so bid farewell to your senses as the love locomotive builds up a head of steam to transport you from the Masked Ball – to The Underworld.

The Underworld is a new concept at the heart of the Masked Ball weekend on a site carved into a cliff top above Porthleven.

Alongside much-loved venues like The Grand Ballroom, and a dozen or so other areas, The Underworld will transport party-goers to a place where fantasy and reality merge, a rollicking-ride through time tunnels to long lost underground clubs in four musical history time capsules.

Will you alight at legendary 1960s Bristol reggae venue The Bamboo Club, or the birthplace of hip-hop - 1520 Sedgwick Ave in The Bronx in the early 1970s. Maybe you'll get to The Blind Pig, a Chicago prohibition-era boogie woogie bar, or lose yourself in New York, in 1978, at the sleazy Coney Island.

Masked Ball director Kelvin Batt said: "The Underworld has been a while in the making and the team is so excited to unleash it. This new addition to the ball is going to be a real showstopper, with all kinds of chaos happening within its walls as you travel through the musical ages.

"We have actors, transvestites, all sorts happening. It's still the same ball, but with a darker underbelly happening within it."

While The Underworld is almost a festival in itself, it forms just part this year's Masked Ball experience, which features nearly a dozen other different venues.

From the glitzy multi-chandeliered and draped Grand Ballroom and The Terrace that overlooks the spectacular Mount's Bay, to the Jelly Jazz Deck and on to the Durty Disco Samurai Stage and the WammaGramma stage, this year's ball will offer more adventures than ever.

Also returning will be The Garden with its twisting trees and revellers will be able to revisit Balls Deeper – at a venue entered via slide into a giant ball pool.

Among the 100 or so acts at the Summer Masked Ball to lay down the wax on the tracks are Hot Chip, Craig Richards, Felix Dickinson, Horse Meat Disco, PBR Streetgang, LTJ Xperience, Honey Soundsystem, Horse Meat Disco, DJ Marky and MC GQ, 45 Live, Austin Ato, Bocawoody, DJ Food, Dicky Trisco and Pete Herbert, Durty Disco, Felix Dickinson, , Justin Robertson, Loose People, Man Power, Norman Jay MBE, PBR Streetgang, Psychemajik, Shit Robot, Spiritual South, Space Echo and Tiger and Woods.

This year's full programme includes Feast Friday in the Grand Ballroom, mixing dinner and disco, followed by the Grand Ball on Saturday, when it's time to party until sunrise, and Sunday Service, for the truly dedicated and decadent.

Tickets for the full weekend, including the Friday feast, are now on sale at £69, and original Masked Ball tickets to include camping for both Saturday and Sunday are £55.
