I'd like to describe the birth of achtung baby for me personally as I remember it:
I hadn't heard anything from u2 since 1988 with rattle and hum. most of that album was rooted in americana. then, in 1990, I heard their cover of night and day and said "whoa; if they make an album like this, it's gonna be amazing".
then I heard nothing for another year. nothing. no internet back then. no magazine articles. no dj's talking about them.
then it happened.
one sunday night in october 1991, I was watching mtv's alternative nation around midnight. the guy says "we've got the world premiere of the new u2 video tonight"
I said "huh?"
and then: my boys come out blasting with the fly. bono, nearly unrecognizable in the fly shades and leather outfit. edge with the goatee, skull cap, and sparkle pants. the video was grainy, mysterious, european, and a little spooky. I loved it immediately.
now, I describe that moment because a moment like that will never exist again for music, because of the internet and the instant information age. there are no surprises anymore, and no spine tingling moments like that.
man, I loved that moment.
