Bono and the rest of U2 might be more about big hair, big sunglasses and big arenas more than political revolution these days, but at one point in time their music didn’t feel so forced. 1991’s Achtung Baby was one of those times. With approximately one bazillion records sold worldwide (it’s actually around 18 million, but who’s counting?), Achtung Baby was a departure from the norm and saw U2 head towards the dark side and get a little more gritty. Don’t just take our word for it though, there’s a reason it’s on lists of “Greatest Albums of all Time” more frequently than it’s not. And now it’s being re-released in three deluxe editions for the twentieth anniversary.
