Professionally filmed video footage of LOCK UP's entire performance at this year's edition of the Hellfest festival, which was held June 15-17 in Clisson, France, can be seen below.

LOCK UP bassist Shane Embury (also of NAPALM DEATH) was unable to make the Hellfest appearance and was temporarily replaced by Dan Lilker (NUCLEAR ASSAULT, BRUTAL TRUTH, S.O.D., VENOMOUS CONCEPT).

LOCK UP's latest album, "Necropolis Transparent", was released in North America in July 2011 via Nuclear Blast Records. The CD was recorded in November-December 2010 at HVR Studios in Ipswich, United Kingdom and was mixed in January 2011.

"Necropolis Transparent" features guest appearances by HYPOCRISY/PAIN mainman (and one-time LOCK UP vocalist) Peter Tägtgren along with Jeff Walker (CARCASS, BRUJERIA).

Commented LOCK UP 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 complement [current LOCK UP vocalist] Tomas [Lindberg; also of AT THE GATES] 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 a part 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!"

According to a press release, "The songwriting and production on ['Necropolis Transparent'] surpasses everything the band has done so far. The speed, riffing and intensity make this record more than just a grindcore album and see LOCK UP come into their own true identity."

Originally formed by Shane Embury (NAPALM DEATH, VENOMOUS CONCEPT), Nick Barker (ex-CRADLE OF FILTH, DIMMU BORGIR) and Jesse Pintado (NAPALM DEATH, TERRORIZER) to blast out the most caustic, skin-flaying brand of deathgrind, LOCK UP was joined by the raw throat of Peter Tägtgren (HYPOCRISY) for its debut album, 1999's fearsome "Pleasure Pave Sewers", and Tomas Lindberg (AT THE GATES, DISFEAR) for 2002's "Hate Breeds Suffering", touring Japan and then falling into inactivity.

Now joined by guitarist Anton Reisenegger (Chile's PENTAGRAM, CRIMINAL) in place of the late Jesse Pintado, LOCK UP is back in the most uncompromising style possible.
