U2’s Achtung Baby marks its 20^th anniversary this year and the Irish rockers are planning to release a deluxe edition of the album to celebrate. The 1991 album also will be paired with U2’s 1993 release, Zooropa, in a special edition box set, according to Rolling Stone – via Slicing Up Eyeballs.

“There will be multiple formats,” said U2 manager Paul McGuinness. “If you pile a lot of extra material and packaging and design work into a super-duper box set, there are people who will pay quite a lot for it, so you can budget it at a very high level and pump up the value.”

The plan is for each album to be issued on its own and that the set will include bonus audio and video material from U2’s ZOO TV concerts.

Last month, it was reported that the band members were filming footage for an Achtung Baby documentary with It Might Get Loud’s Davis Guggenheim.
