In 2018, the group followed it up with The Naughty Corner EP, spearheaded by sadistic lead single Redline Reaper and the daintier Tarlo. Switching between hard-headed trap music and melodic moments with rapid confidence, The Naughty Corner is even more evidence that Triple One are speeding down a lane of their own. Their 2018 singles Tarlo, Valentine Kid & Showoff were added to rotation on triple j, gaining additional praise from FBi Radio, Purple Sneakers, Pilerats, Highsnobiety and more. In June, Triple One were crowned the triple j Unearthed Feature Artist of the Week.
The group's demonic spirit comes to life in fiery form onstage, with Triple One’s debut tour in July 2018 selling out convincingly. Rambunctious shows in Melbourne, Brisbane & their native Sydney have resulted in mosh pits and widespread mayhem, earning Triple One a notorious live reputation.
