Half Sumo, the Brooklyn-born art collective that blends the ferocity of combat sports with the rebellious spirit of streetwear, today announced a landmark collaboration with thrash metal architects MEGADETH. This ground-breaking partnership celebrates the 40th anniversary of the band’s genre-defining debut album, “Killing Is My Business… And Business Is Good!”

The alliance is a testament to the shared discipline and aggressive artistry that fuels both worlds. MEGADETH frontman Dave Mustaine, a lifelong martial artist, holds black belts in Taekwondo and Ukidokan Karate, as well as a brown belt in Brazilian Jiu-Jitsu, making this collaboration a deeply authentic one.

Forty years after its release, the raw power of “Killing Is My Business…” remains a benchmark in metal. The Megadeth x Half Sumo capsule honors this legacy with a collection of wearable art that reimagines the album’s iconic imagery through the lens of samurai lore, urban warfare, and underground resistance. For the first time ever, MEGADETH‘s iconic mascot, Vic Rattlehead, will be emblazoned across a full range of premium fightwear, including custom nogi rashguards, shorts, and a highly anticipated, master-crafted kimono.

“To see the raw energy of our first album translated into gear that’s built for the mat is a thrilling moment,” said Mustaine. “Half Sumo honored the spirit of ‘Killing Is My Business…’ perfectly.”

“MEGADETH‘s debut was a declaration of war on the status quo,” said Half Sumo founders Luigi Scarcella Perino and Alberto Marchetti. “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 will be released in four highly limited waves at HalfSumo.com.
