HSU — Adelaide event promoter

HSU aka Harder Styles United

HSU Events, short for Harder Styles United, is a Sydney hard-dance promoter established in 2009. It began with monthly Friday parties at The Gaff on Oxford Street, where Toneshifterz and Bioweapon played to a growing following. HSU later moved from club nights into large festivals and now runs some of the Southern Hemisphere’s biggest harder-styles events. Its brands include Knockout Outdoor, Midnight Mafia, EPIK and HTID, covering hardstyle, rawstyle, hardcore, uptempo, happy hardcore and related sounds. The company has staged events in Australia, Spain, the United Kingdom, Chile and the United States, while HSU Live extended its work into streamed performances. In Adelaide, HSU works with Project Hardstyle on tours, including Dual Damage at Hindley Street Music Hall and Rooler’s all-night set. Known for arena-scale staging, themed productions and international bookings, HSU has grown from a Sydney basement party into one of Australia’s largest independent electronic event organisers.
