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) - have been forced to cancel their appearance at this year’s Maryland Deathfest (May 26th - 29th).

The band has released the following statement: “We regret to announce that Lock Up will not be performing at this year’s MDF. We are days away from the festival and our visas have yet to show up. Everything has been handled the right way but apparently things are taking longer these days due to a larger amounts of red tape and bureaucracy. We hope to make things up shortly when our visa actually arrive with some North American tour dates!”

Lock Up will release their new album, Necropolis Transparent, on July 1st via Nuclear Blast Records as a regular CD, black vinyl and transparent vinyl. The CD was recorded in late 2010 at HVR Studios in Ipswich, UK and was mixed in January.

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!"
