Ace of Base is a Swedish pop group from Gothenburg, known for having one of their biggest and most famous hits with "All That She Wants." The main initiator behind the founding of Ace of Base was Jonas Berggren. He had previously worked for several years in a band called G Konrad and then, in 1987, formed a techno band with two friends that did not achieve international success. He was able to recruit his two sisters, Malin and Jenny, as singers for this band. However, the band disbanded when the two partners left. Jonas was able to bring his friend Ulf Ekberg on board for a fresh start. This completed the quartet, which formed as Ace of Base in 1990.
