The inaugural Freesports on 4 Freeze ignores the capital's lack of snow and takes over Battersea Power Station for a three-day alpine sports festival. Two big-air competitions pit UK Olympic hopefuls against the world's best pro riders, with the skiers out Friday and the boarders going stratospheric on Saturday. Cypress Hill lead the boom-heavy live entertainment along with the Enemy, grime MC Sway and estimable rockers the Ghost Frequency. Product fiends can browse the latest snow attire and the après bars promise vin chaud if the temperature drops to Baltic levels.
