Which U2 album was primarily recorded at Hansa Studios in Berlin and in Dublin?

U2's album primarily recorded at Hansa Studios in Berlin and in Dublin was Achtung Baby. The sessions marked a major change in the band's musical direction.

U2 began work on the album in October 1990 at Hansa Studios in Berlin, a location associated with important recordings by David Bowie and other artists. The band later continued recording at Dublin facilities, including the seaside mansion known as Elsinore.

The project was initially difficult, with disagreements about musical style and arrangements. The resulting album, released on 18 November 1991, combined alternative rock, electronic textures, dance influences, and layered production. Its songs included “One,” “The Fly,” and “Mysterious Ways.”
