Chicago hardcore mob Rise Against have now completed work on their sixth studio album.
The record, which will be titled Endgame, will be released in the UK on March 14.
While the band have been keeping much of the album's details to themselves, Alkaline Trio frontman Matt Skiba confirmed on Twitter yesterday that he was guesting on the record.
"Sang on Rise Against's new album this morning at 10AM in Tarzana with Bill Stevenson producing," he wrote before later adding: "Back at the studio with Rise Against/Bill Stevenson. They asked me to sing more stuff. They like me... They REALLY LIKE ME! Psyched. Great songs!"
