AC/DC have announced plans for a tour to celebrate their 40th anniversary.
The Highway To Hell rockers also revealed they have begun work on their first new album since 2008's Black Ice, according to Rolling Stone.
Frontman Brian Johnson told Florida radio station Gater 98.7: "Its been 40 years of the band's existence. So I think we're gonna try to do 40 gigs, 40 shows, to thank the fans for their undying loyalty. I mean, honestly, our fans are just the best in the world, and we appreciate every one of them. So, like I said, we'll have to go out, even though we're getting a bit long in the tooth. You know what? It's been four years, and I'm really looking forward to it."
Brian also revealed the band would be heading to a Vancouver studio in May to record their 16th studio album.
