Happy Nation is the debut album by the Swedish pop group Ace of Base. It was initially released in Denmark on 2 November 1992 by Mega Records. During the album's development, the group was significantly influenced by a Jamaican reggae band that was recording in a nearby studio. For its release in North America, Japan, and some Latin American countries, the album was retitled The Sign, featuring a heavily revised track listing along with three new tracks. To coincide with this, Happy Nation was reissued with the new tracks in other territories under the title Happy Nation (U.S. Version).

The Sign is a 1993 album by Swedish pop group Ace of Base, released as the band's debut album in North America, Japan, and some Latin American countries by Arista Records.

The Bridge is the second album by Swedish pop music group Ace of Base. It was composed during 1994 and 1995, and released in October 1995. It is the only Ace of Base album to feature sizable contributions of writing, production, vocals, and harmonies by all four band members, each having an important part in its creation.
The album was preceded by the singles "Beautiful Life" and "Lucky Love", which had varied levels of success. Both songs reached the top of the US Billboard Hot Dance Club Play chart and "Beautiful Life" peaked at number 15 on the US Billboard Hot 100, "Lucky Love" reaching number 30. Following the release of the album, "Never Gonna Say I'm Sorry" was released as the third and final single from the album but failed to gain recognition due to a lack of promotion.
