Prosper Unger-Hamilton turns alt-J's trip to the skatepark into an acid-fuelled fever dream for U&ME, the first release from the band's long-awaited fourth album.Inspired by '90s skate videos, Unger-Hamilton - brother of bandmember Gus - incorporates inspired use of visual effects into his lo-fi footage filmed at Romford skatepark, riffing on the classic paranoia of the stoned skater, both before and after a horrible faceplanting smash by singer Joe Newman.With gigantic bowls, towering ramps, incoming twisters and crumbling asphalt, Unger-Hamilton visualises some unspoken skater-fears in a mesmeric, dreamlike style reminiscent of early DANIELS and BRTHR videos.And as well as achieving that rarity of having alt-J themselves appearing in their own video, he even gets a murmur of lipsync in there too, from the facially-injured Newman.
