Sylosis

Josh Middleton’s Sylosis is proof that technical thrash is shedding its nostalgic skin. While the UK outfit has long been a musician's favorite, their upcoming 2026 arena tour support for Killswitch Engage signals a transition from cult technicality to primary-stage visibility. Unlike their peers who lean into over-production, Sylosis maintains a raw, aggressive velocity that feels increasingly relevant as metal audiences pivot back toward authentic proficiency. We’re watching to see if this high-profile visibility converts their rising conviction into a definitive genre-leading position.
