Achtung Baby - Recording and Production

Recording and Production

"Buzzwords on this record were trashy, throwaway, dark, sexy, and industrial (all good) and earnest, polite, sweet, righteous, rockist and linear (all bad). It was good if a song took you on a journey or made you think your hifi was broken, bad if it reminded you of recording studios or U2. Sly Stone, T. Rex, Scott Walker, My Bloody Valentine, KMFDM, the Young Gods, Alan Vega, Al Green, and Insekt were all in favour. And Berlin ... became a conceptual backdrop for the record. The Berlin of the Thirties—decadent, sexual and dark—resonating against the Berlin of the Nineties—reborn, chaotic and optimistic..."

U2 hired Daniel Lanois and Brian Eno to produce the album, based on the duo's prior work with the band on The Unforgettable Fire and The Joshua Tree. Lanois was principal producer, with Mark "Flood" Ellis as engineer. Eno took on an assisting role, working with the group in the studio for a week at a time to review their songs before leaving for a month or two. Eno said his role was "to come in and erase anything that sounded too much like U2". By distancing himself from the work, he believed he provided the band with a fresh perspective on their material each time he rejoined them. As he explained, "I would deliberately not listen to the stuff in between visits, so I could go in cold". Since U2 wanted the record to be harder-hitting and live-sounding, Lanois "push the performance aspect very hard, often to the point of recklessness". The Lanois–Eno team used lateral thinking and a philosophical approach—popularised by Eno's Oblique Strategies—that contrasted with the direct and retro style of Rattle and Hum producer Jimmy Iovine.
