I love the cold, abrasive, unforgiving sound of the War album. Dated? I dunno. But it doesn't sound like a victim of production. It just sounds bleak, wintery. I love that about it though.
EXACTLY!
It fits the theme of the album- War! The Cold War, The Troubles in Ireland, poverty, broken relationships and love amidst all of it(Surrender, 2 Hearts).
As GVOX said quite well, it isn't a sound that really is at home with U2's contemporaries as they existed in 1983.
Maybe I'm biased, as I think War is bested only by JT and AB in the U2 catalogue!
