Snowbombing, dubbed Ibiza on Ice, the biggest and most established of the frosty festivals, is set to be mightier than ever with Fat Boy Slim, 2ManyDJs, Editors and Friendly Fires headlining the six-day bash in Mayrhofen, Austria, and party princess Jade Jagger hosting its Arctic Disco — a giant party igloo 10,000ft up a mountain, complete with a DJ booth carved into the ice. The line-up of The Brits festival in Laax, Switzerland, is soon to be announced, while Altitude festival, also in Méribel, throws laughter into the mix, with comedians including Andrew Maxwell and Phill Jupitus as well as music from acts such as Newton Faulkner and The Cuban Brothers.
