British thrashers ONSLAUGHT — who are celebrating their 30th anniversary in 2013 — have set September 13 as the European release date for their sixth studio album via AFM Records. The follow-up to 2011's "Sounds Of Violence" is once again being recorded, mixed and co-produced by Jacob Hansen at Hansen Studios in Ribe, Denmark.Comments the band: "What a totally crazy week this has been in the ONSLAUGHT camp! Nige Rockett and Andy Rosser-Davies have completed the recording of all 36 rhythm guitar tracks for the new 'SLAUGHT album, Mic Hourihan has completed all the drum tracking (which I can honestly say sounds truly fucking explosive!!). Things are rocking harder than we could have ever imagined right now... "In other news, we are extremely stoked to welcome Pär Olofsson on board as the band's artist for the new album sleeve. The first rough sketches are awesome and in a very different style from every other album cover we have made. [We] can't wait to see the final design! "Also been speaking to a very good friend and A&R guy from London Records-era about something which is very very interesting, and to cap off the week of madness, we are to take part in the longest in-depth interview we have ever done with our friend Laurent from Snakepit fanzine... No rest for the wicked." 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. 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.
