Wakestock

Calvin Harris, Rizzle Kicks, Flux Pavilion, High Contrast (Fri); Dizzee Rascal, Katy B, Annie Mac, Ms Dynamite, Jakwob, Doctor P (Sat); Ed Sheeran, The All-American Rejects, Redlight, Goldierocks (Sun). Part music festival, part wakeboarding comp and part student piss-up by the sea, the sonic entertainment at this beach party split over three sites in North West Wales tends towards youth-pleasing electronica and urban, plus a clutch of alt.indie artists. And Ed Sheeran.
