Biffy Clyro: First number one album gave us confidence
Biffy Clyro have described having their latest album reach number one in the UK album chart as a "real confidence boost".
Frontman Simon Neil said he had surprised himself with how much the achievement meant to the Ayrshire band.
The trio's double-disk album, Opposites, topped the charts in February 2013. It was their first number one album.
"I was more over the moon about it than I thought I would be," admitted Neil.
Speaking to Newsbeat at the NME awards Neil said: "I thought I'd be able to take it in my stride and think, 'Cool, it doesn't mean anything.'
"But, I think it did mean something to a band like us who've built up from being like 13 years old together, just playing and making everything happen organically.
"To make a double album which made it to the top of the charts is something we can't quite get our heads around.
"It was unbelievable. I didn't think we'd be so excited about it - when we found out about it we had the week of our lives."
Biffy Clyro will begin a UK headline arena tour in Newcastle on 20 March.
It was recently announced that the band would headline the Reading and Leeds festival in August.
