“Well, I was in the minority there, being an old dude for one! But it was two sold-out nights at the Friends Arena which holds 60,000 people or something. My oldest daughter likes One Direction, and I anticipated some type of show as they had some elaborate stage thing going on.

“But when the guys hit the stage it kinda felt like they’d just dragged five guys from the crowd up… if there were guys in the crowd, which there obviously wasn’t! It was just people on stage that were able to sing in key, but other than that they didn’t do much, they didn’t do any syncopated dance moves, there wasn’t much of a show. And since there were five guys, they’d sing every fifth line of a song and in between be just walking around.

“For me, it was mind-boggling, I just couldn’t see the fascination, but kids think they’re cute and that kind of stuff. For me, I did not understand the point of the songs… some I recognised but I felt a bit sad in a way. Story Of My Life is the good song, I turned to my daughter and said, ‘This one’s okay.’”

Earlier, Opeth frontman Mikael Akerfeldt said he hasn’t managed to persuade his kids to start following heavier music. And he admits parenthood has taken some of the wind out of his sails when he’s on the road.

Akerfeldt tells TeamRock Radio: “Being a dad and being away so much is difficult. It’s not as fun to be away when you have kids.

“In the early days touring was partying, rocking out and having a good time. Now I kind of approach touring as work.”

He continues: “I’m sure sure it has changed the music. Things around you change when you have kids. I’m taking my daughter to see One Direction. Right now both of them are into Grease, the musical.”

Opeth are gearing up for the release of 11th album Pale Communion – but the mainman says there’s no big meaning behind the title.

“It’s kind of difficult to come up with album titles,” he reports. “I want them to sound cool and look cool and fit in with my lyrics. I was going through my lyrics and it felt like a fitting title for me, but it doesn’t really mean anything.”
