ITUNES FESTIVAL: 5 Seconds Of Summer + Charlie Simpson

A young boy band who formed in Sydney in 2012, 5SOS toured with One Direction for six months but (unlike the 1D boys) play their own instruments and write their own songs: think Busted, but from Down Under. This slot at the iTunes Festival (ahead of a Wembley Arena gig in 2015) hints at bigger things to come. At the opposite end of the boyband career trajectory, former Busted singer Charlie Simpson plays a support set. To win tickets, enter at itunes.com/festival.
