Liverpool hardcore punk Violent Reaction's relocation to Leeds in the early-2010s, led to the city becoming one of the main locations for the then-emerging New Wave of British Hardcore (NWOBHC) scene. Merging elements of UK82 and oi! into the sound of hardcore, the NWOBHC continued to grow in the city, where groups like the Flex, Regiment, True Vision and Shrapnel became prominent practitioners. The Temple of Boom (now called simply Boom) on Millwright Street quickly became the most prominent venue within this scene. Opened in 2011 by Voorhees Ian "Lecky" Leck and Sean Walker, the venue began as a rehearsal studio, before beginning to put on performances after being pushed to by the members of the Flex. Former Violent Reaction and Shrapnel member Jimmy Wizard formed Higher Power in 2014, with his brother Alex, which eventually grew to include additional members Louis Hardy, Max Harper and Ethan Wilkinson. Metal Hammer hailed the band as "the band redefining hardcore for a new generation", and are the second UK hardcore band to have signed to a major label, in the form of Roadrunner Records. In 2016, Vice described Leeds bands like Rapture, Shrapnel, True Vision and Regiment as "the Second Coming of UK Straight Edge Hardcore". Higher Power members Alex Wizard and Louis Hardy, Violent Reaction guitarist Tom "Razor" Hardwick and Rapture guitarist Maegan Brooks formed Big Cheese, who gained prominence in the late-2010s, along with groups like Scorned and Greed. Outbreak Festival, which for much of its existence has been held at Canal Mills in Armley, is a key location for the hardcore scene, and most features local groups like Higher Power, as well as international groups like Code Orange, Turnstile and Vein.
