The award-winning, Wilderness festival, has today expanded its dynamic musical line-up for 2013, welcoming an array of exceptional talent to its carefully curated main stage. This year it is proud to welcome the raw talent of Martha Wainwright, along with, Sam Lee, The Bees and London Grammar.

Folk-rock singer, Martha Wainwright, will set the stage alight with her compelling vocals and poignant lyrics. Following the release of her third album, “Come Home To Mama” at the end 2012, Wainwright has once again wooed critics with her soulful and charismatic performances.

Mercury-nominated Sam Lee will be bringing his own daring twist of contemporary and traditional folk to this year’s main stage. Pioneering a new colourful style of folk music, inspired by his own exploration into Roma, Gypsies and travellers music, Sam Lee has certainly shaken up the genre and will be one to watch.
