There indeed were other albums that came out 20 years ago besides Nirvana’s soon-to-be reissued Nevermind. One such record marked U2‘s sea change — the seminal 1991 release of Achtung Baby. By enlisting Daniel Lanois and Brian Eno to produce, the band’s sound incorporated electro, industrial, hip-hop, and all of a sudden we’re. . . dancing to Bono. You can relive those moments, along with whatever moments you happen to cherish off of their 1993 release Zooropa, later this fall (via Slicing Up Eyeballs).

A Rolling Stone piece, referenced by the @U2 fansite but not yet available online, quotes U2 manager Paul McGuiness: “There will be multiple formats. 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.” Thanks, Paul, for reminding us that these kinds of things really are all about the music and the art.

The article states that they are “likely” to be released this fall and combined into a box set featuring bonus audio and video assets from their ZOO TV era. Additionally, Rolling Stone reports that U2 is working on an app “for the iPad and other tablets that could be involved with the releases.”

Enough commerce. Check this video of The Edge intoning on “Numb” from the ZOO TV Tour:
