American pop punk crew The Wonder Years have announced a sideshow alongside their appearance at Soundwave. Following on from their critically-praised piece Suburbia I’ve Given You All and Now I’m Nothing, the boys from Pennsylvania have announced a huge show alongside genre buddies Living With Lions (whose album Holy Shit perfectly suits how many critics have reacted to it) and melodic hardcore band Such Gold. Featuring members from Lagwagon and The Ataris, Versus The World will also be joining this powerful bill.
