Extreme metal supergroup LOCK UP - featuring singer Tomas Lindberg (AT THE GATES, DISFEAR), bassist Shane Embury (NAPALM DEATH, VENOMOUS CONCEPT), drummer Nick Barker (ex-CRADLE OF FILTH, DIMMU BORGIR) and guitarist Anton Reisenegger (PENTAGRAM, CRIMINAL) - will release their new album, Necropolis Transparent, on July 1st in Europe, and July 12th in North America via Nuclear Blast Records as a regular CD, black vinyl and transparent vinyl.

Check out a near-ten minute album preview below:

Producer Andy Sneap (MEGADETH, TESTAMENT, ARCH ENEMY) commented: “Having known Nick and Shane (a.k.a. the sumo tag team of grindcore) since the late 80's its always great to get together with old friends and make some noise in the studio. Necropolis Transparent by far, surpasses what we achieved together back in 1999 with Pleasures Pave Sewers in terms of brutality, speed and song writing along with the help of new guitarist Anton Reisenegger. For me personally ,it was quite refreshing and great fun to do something this extreme, especially with my mates Nick, Shane and Carcass mainman Jeff Walker swinging by the studio to handle guest vocal duties and help us drink way too much. I have to say that Necropolis Transparent is way more than just another grindcore album, it has elements of everything that represents brutal and extreme-An absolute MUST for everyone out there that like their metal full of aggression, violence and pure savagery. BUY OR DIE!!!”

Necropolis Transparent will feature several guest appearances from HYPOCRISY/PAIN mainman (and one time Lock Up vocalist) Peter Tägtgren along with Jeff Walker (CARCASS, BRUJERIA).

Commented bassist Shane Embury: “I always wanted Peter on the third album since he was on the first record Lock Up we did. It made sense from a weird trilogy aspect to get him on the record. His tones compliment Tomas perfectly as well. I would have loved to have had Peter sing on more of the songs, but time was short as Peter was heavily involved with his new Pain record. The songs he did sing on though made them extra special. As for Jeff, well me and Jeff go so far back it's unreal. We were mixing the album at Andy Sneap's and I wanted an extra vocal texture on a few tracks to spice it up. My voice is more hardcore and I wanted some extra gravel on things. It all seemed to make sense to Jeff once I had bribed him with a 12 pack of his favorite beer (laughs)!”

“It’s great that Lock Up is back in the saddle again and that I could be apart of it,” commented Peter Tägtgren. “This album will tear you a new asshole!”

Jeff Walker added: "I think it's pretty fair to say that the current incarnation of Lock Up have done the late Jesse Pintado more than proud!"
