In honor of the 20th Anniversary of "Achtung Baby" U2 has released a massive boxed set filled with outtakes, b-sides, unreleased cuts, and remasters.
Disc 6 is the most interesting. Called "[I]Kindergarten - The Alternative Achtung Baby[/I]" it's an alternate track-for-track version of the whole LP with songs that are in their early stages, songs with alternate lyrics, songs stripped down, etc.
Here's a link where you can hear each song:
A great listen for U2 fans.
Did you pick this up? I'm curious as to how well the remaster of the album proper sounds.
