Thrash metal pioneers Megadeth have forged a unique partnership with Half-Sumo, a fightwear brand, to release an exclusive line of merchandise. This collaboration fittingly commemorates the 40th anniversary of Megadeth‘s seminal debut album, Killing Is My Business… and Business Is Good!. The collection deeply resonates with Megadeth frontman Dave Mustaine‘s extensive background in martial arts, as he holds black belts in Taekwondo and Ukidokan Karate, alongside a brown belt in Brazilian Jiu-Jitsu.
Dave Mustaine expressed his enthusiasm for the project, noting how the new gear perfectly embodies the album’s intensity. “To see the raw energy of our first album translated into gear that’s built for the mat is a thrilling moment,” he said. “Half Sumo honored the spirit of Killing Is My Business… perfectly.”
Half-Sumo founders Luigi Scarcella Perino and Alberto Marchetti echoed this sentiment, highlighting the shared aggressive and boundary-pushing spirit between Megadeth‘s music and their brand. “Megadeth‘s debut was a declaration of war on the status quo,” they stated. “It was technically brilliant, unapologetically aggressive, and it set a new standard for heavy music. That is the same energy we inject into our gear—the spirit of the underdog fighting a bigger battle. This collection is for them.”
The Megadeth x Half Sumo Killing Is My Business… and Business Is Good! 40th Anniversary capsule is being rolled out in four distinct, highly limited waves. The initial wave is already available.
