Last night (March 26), Carcass performed for the first time with its new lineup at the Underworld in London. While we knew that guitarist Bill Steer and bassist/vocalist Jeff Walker had been joined by drummer Daniel Wilding of Trigger The Bloodshed, the show confirmed that Carcass’ new touring second guitarist is Ben Ash (Pig Iron, Desolation, Liquefied Skeleton). Unsurprisingly, fan filmed footage of the show has made its way online. Check out one clip above.

Carcass is currently putting the finishing touches to Surgical Steel, the group’s first album since 1996’s Swan Song. The album has received a bit of drama thanks to producer Colin Richardson, who quit the project two weeks into mixing. Walker previously told Colombia’s El Santuario Del Rock that Richardson was simply “burnt out.” However, during last night’s show, Walker told the crowd that the producer actually quit to mix Trivium’s new album. Talk about escalating drama, eh? The band has since brought in Andy Sneap to mix Surgical Steel, due out later this year via an as-yet-determined label.

Video of Walker claiming Richardson quit to mix the new Trivium album, along with more footage from the show itself, can be seen after the jump.
