UK thrashers ONSLAUGHT have set Friday, September 13 as the worldwide release date for their sixth studio album via AFM Records. The follow-up to 2011's "Sounds Of Violence" will once again be recorded, mixed and co-produced by Jacob Hansen at Hansen Studios in Ribe, Denmark, with work set to commence on May 18.Commented ONSLAUGHT guitarist Nige Rockett: "It's awesome to be making another album with Jacob Hansen. There was never gonna be anyone else considered, simply because of the way Jacob works on a personal level and the incredible dynamics of his final mixes. We just know it's gonna be totally immense. "The writing is 90% complete and it's sounding very, very cool. I'm not gonna say it's 'louder, faster, heavier’ than anything we've ever done because that's a little bit cliché these days. All I will say is that it's very fresh, it's old school and it's ferocious. The rest we'll leave up to you guys to decide." ONSLAUGHT will headline the first Slaughterfest across Europe in October, with German cult thrashers EXUMER, MPIRE OF EVIL and death metal legends MASTER completing the bill. Fans will have the opportunity to take part in meet-and-greet events on selected dates. ONSLAUGHT's last tour saw the band performing its 1986 album, "The Force", in its entirety. The band also recorded a new version of its classic song "Metal Forces", for inclusion as a bonus track on the re-release of the band's 1986 album, "The Force", available on AFM Records. The set contains revised artwork and some sleeve notes written by Rockett. ONSLAUGHT is tentatively scheduled to enter the studio at the end of the year to record its new album for a spring release via AFM Records. The band's fifth album, "Sounds Of Violence", was released in January 2011 via AFM Records. ONSLAUGHT recruited Michael Hourihan (EXTREME NOISE TERROR, DESECRATION) to play the drums following the departure of Steve Grice in 2011.
