Four friends from South London formed Palma Violets on a trip to Reading Festival, out of frustration at the lack of authentic music around them. Not long after their return to Lambeth, Sam, Chilli, Pete and Will were attracting the attention of Rough Trade Records and the NME, who slapped the fledgling Violets on the cover of the magazine after falling in love with "top track of 2012" Best of Friends. Famed for their raucous live sets, the foursome have taken to the pressures of saving British guitar music with ease. They've toured debut album 180 on both sides of the Atlantic, in an assiduous six months of winning friends and sharpening sets. The Park Stage performance will be a highlight in a hectic summer that will surely see them make the step from indie upstarts to leading lights.
