Linn Berggren

During the promotion for Ace of Base's first album, Linn was the principal lead vocalist for the majority of the singles and was generally the focus in the videos, although on some singles ("The Sign", "Waiting for Magic") and album tracks Jenny and Linn shared leads. Linn had a somewhat minor role in the composition of Happy Nation and The Sign, only having co-writing credits on one track on a re-release of the former. She was influential in the development of "All That She Wants", demanding that the track be changed from major key to minor.

In 1994, a German girl invaded the Berggren family home, targeting Linn. Linn was not present, but the girl attacked Jenny and her mother with a knife. This incident had a large impact on Linn.

During the release of the group's second album, The Bridge, the focus in both vocals and media became more equal with her younger sister, Jenny. Linn had a larger role in the composition of The Bridge and wrote and produced several songs for the album. Following the completion of the album, it was reported that Linn developed unspecified recurrent vocal problems.
