Back in May, NME spoke to Biffy Clyro on the red carpet at the 2021 BRIT Awards, where the band revealed that they had finished their new album the previous week.

Asked if the LP could still be considered a “sister record” to its predecessor, Neil replied: “Originally it was going to be completely hand-in-hand. They do relate, but because we didn’t tour I ended up writing about seven or eight new songs for the album. Originally it was intended to be a few off-cuts from ‘A Celebration Of Endings’, but now it’s got wonderful new art and it’s kind of its own beast.

“The lyrics correspond at certain points and there are a lot of Easter eggs for fans in there, but it’s a proper record. It’s not like we headed in, rushed it and banged out a few songs – it has become this epic ‘meister werke’, if I can say that about our band, which I can’t. I’ve turned full dickhead now! I’m sorry.”
