The "Eno-Lanois" sound is built on layers. Unlike the direct punch of their earlier work, this album features:

: A frantic, jagged track that showed the band hadn't lost their edge—just refined it. Closing Thoughts The Unforgettable Fire

: Brian Eno introduced the Yamaha DX7 synthesizer to add dreamy textures, while The Edge expanded his guitar palette using a Lexicon Prime Time delay unit and an EBow for a shimmering, "out-of-focus" effect.
