Mass Mental is a project helmed by Metallica bassist Robert Trujillo and Benji Webbe of Skindred. It had already been announced that the metal musicians would be joined live by Paul Simon collaborator Armand Sabal-Lecco, Whitfield Crane of Ugly Kid Joe and Brant Bjork of Kyuss at the show, which takes place at the Electric Ballroom in Camden, north London on Sunday (March 13).
As Blabbermouth reports, Campbell will also appear live with the group. The show has also been upgraded from its original venue of the nearby Underworld.
Campbell had been Motörhead’s guitarist since 1984. He was unable to attend the funeral of frontman Lemmy, who passed away last December.
Explaining his absence, Campbell tweeted that he “really wanted to attend but I wasn’t able to make it”. He added: “Unfortunately I was advised on doctors orders not to fly on such a long haul flight due to my recent hospitalisation”.
Lemmy passed away on December 28 following a short battle with cancer. He was aged 70.
His funeral was held in Los Angeles on January 9, with Dave Grohl, Slash and more in attendance.
