I apologize ahead of time if this topic has already been discussed to death. (I'm sorry)
U2 albums with their re-release date, anniversary info, and remaster info:
November 2007 The Joshua Tree (20th Anniversary) (Remastered)
July 2008 Boy (no anniversary) (Remastered)
July 2008 October (no anniversary) (Remastered)
July 2008 War (no anniversary) (Remastered)
October 2009 The Unforgettable Fire (25th Anniversary) (Remastered)
October 2011 Achtung Baby (20th Anniversary) (not remastered)
October 2011 Zooropa (re-released with Achtung Baby) (no anniversary) (not remastered)
Why would any other albums be re-released?
A. Because of un-released tracks?
When the U2 digital box set became available on iTunes in November 2004, I thought, “Well, this is awesome! We have been given every un-released track that U2 has ever recorded.”
I was wrong. Three years later . . . . . . in November 2007, when The Joshua Tree was re-released, we got tracks like wave of sorrow (birdland) and rise up. And in July 2008, when October and War were re-released, we got tracks like tomorrow [common ground remix] and angels too tied to the ground. And in October 2009, when The Unforgettable Fire was re-released, we got tracks like disappearing act and yoshino blossom. And in October 2011, when Achtung Baby was re-released, we got tracks like oh berlin and near the island.
B. Because of re-mastering?
To be honest, I can’t tell the difference between the original and the remastered versions.
So, here are my questions:
Question #1. Why would any other albums be re-released?
Question #2. Would there be an anniversary associated with them?
Question #3. Would they be remastered?
