Grammy Award-winning soul artist Macy Gray is the first of three of their main stage headliners.

Macy Gray shot to international fame in 1999 with the hit single ‘I Try’ and has since amassed an impressive résumé including two Brit Awards, a Grammy Award and a thriving acting career – appearing in films such as 2002’s blockbuster Spider-man.

Macy is set to release her sixth studio album – Covered – on 26 March; a collection of cover songs reinterpreting material by acts as diverse as Metallica, Radiohead, Arcade Fire and Yeah Yeah Yeahs in her compelling and unique vocal style.

Festival organiser Paul Stephen said: “Macy Gray is quite a coup and we’re over the moon to have her confirmed to be one of the three big headliners.”

West London indie musician King Charles, who is creating a stir in the music world at the moment having won the International Songwriting Competition in 2010, will also play the main stage. King Charles, known for his distinctive Victorian costume dress and alternative, folk-pop sound has toured with Mumford & Sons.

Scottish alternative folk-rock band, Kassidy, and Irish indie-rockers, General Fiasco, will also appear along with the legendary country guitar virtuoso Albert Lee and his band Hogan’s Heroes.

Fast rising singer-songwriter Josh Kumra, who recently had a number one collaboration with Wretch 32, will also be on the bill.

The Other Stage will see legendary 2-Tone ska revival band, The Selecter, alongside Nottingham power trio, Little Barrie (whose members include Primal Scream guitarist Barrie Cadogan) and the bizarre electro-swing outfit Kitten and the Hip.

The Dance Stage will feature a live set from Dutch music production duo Mason, two times UK DMC Champion JFB and Sir Spyro, the official DJ for UK Grime artist Tinchy Stryder
