"I would say we had the best three weeks in the studio that we've had since, like, 1979. Three weeks is all it should take."
- Bono on recording a new album, June 2012
The Unforgettable Fire album title is a reference to "The Unforgettable Fire"—an art exhibit about the atomic bombing of Hiroshima. The band saw the exhibit in November 1983 in Japan while on the War Tour.
