LOS ANGELES - When U2 producer Danny Lanois and the band made "The Unforgettable Fire" in 1984, they recorded it at an Irish castle because they wanted a place with history, which Lanois said suited him just fine. The album, which will be re-released on Tuesday in a remastered 25th anniversary edition, marked the first time U2 worked with Brian Eno and Lanois, two producers who would collaborate with the band several times more, and not always in a conventional studio setting.
