Ace of Base is a pop ban from Gothenburg, Sweden, comprising Ulf Ekberg (Buddha) and siblings Jonas Berggren (Joker), Jenny Berggren (and, formerly, Malin "Linn" Berggren). They released their debut album in 1993 and went on to achieve major chart success throughout the 1990s. The departure of former lead singer Linn Berggren was revealed in 2007 after years of declining participation in the group. The three remaining members are currently on a world tour and plan to release a new studio album later in 2008.
