Sonicmania 2015

Held as a warm-up for Summer Sonic each year, the all-night Sonicmania party caters to dance kids who aren't so well served by the main festival itself. This year's edition will see appearances by the likes of veteran electronica juggernaut Prodigy, Marilyn Manson, EDM loudmouths Krewella and trippy DJ/producer Dillon Francis, plus Japan's very own '90s dance warhorses Denki Groove. Tickets go on general sale May 30.
