UK thrash metal legends Onslaught are super stoked to announce the return of their legendary vocalist and fans’ favourite Sy Keeler.
Keeler makes his comeback to the band after a 6-year hiatus and will hit the ground running as the band make their long awaited debut tour of Australia in November 2025; his first appearance back will be at the UK’s Damnation Festival at the BEC Arena, Manchester on November 9.
Kicking off Onslaught’s live season 2026 will be their freshly announced Winter 2026 “The Force From Hell” European run. All dates & ticket info can be found below!
Guitarist Nige Rockett comments: “Wow, this is truly incredible having Sy back in the Onslaught camp. He has always been seen as ‘THE’ Onslaught vocalist and we know the fans are gonna be blown away for sure. The band are in a truly great place right now after the success of the ‘Origins Of Aggression’ release and this will be seen as amazing news, I’m sure”.
Sy states: “Well, that came out of nowhere! ‘Sy, would you consider rejoining the band?’! ‘Ugh! Yes, of course, I’ve really missed it’. So almost 6 years on from my last gig, I’m very excited to be embarking on the 3rd chapter, looking forward to meeting old friends and of course making new ones, and of course having a few beers with my band mates. See you on the road very soon metalheads”!
Continuing the explosive success of their still ongoing “Power From Hell” tour and their career-defining double-album “Origins of Aggression” (released on May 23rd, 2025 via Reigning Phoenix Music), the band are ready to turn the pit into chaos once more with their “The Force From Hell” tour. In early 2026, they’ll be bringing the ultimate thrash assault to 22 cities all over the continent – a full-on fusion of their iconic debut “Power From Hell” and the 40th anniversary celebration of “The Force”.
Onslaught comment on their upcoming tour: “So looking forward to this one following on from the great success of the ‘Power From Hell’ tour earlier this year: it’s gonna be a full on combination of the best of ‘Power From Hell’ with ‘The Force’ [40th anniversary] to create a totally monstrous set for those who we missed out last time… Let there be thrash – see you in the pit”!

“Origins of Aggression” is a 22-track double album that dives deep into Onslaught’s history, delivering fierce new takes on early classics alongside covers of key influences such as Motörhead, Dead Kennedys, and Discharge.
Onslaught’s contribution to the thrash metal genre cannot be overstated: from their debut album “Power From Hell” [1985], which is being honoured with their new release, to their celebrated performances across the globe, they remain an untouchable force in the world of heavy metal. With over 40 years of history, the quintet have steadily continued to evolve, delivering relentless riffs and neck-breaking anthems, and cementing their place as pioneers of the British thrash scene.
