Sweden is a country where dance music and pop music are very popular. In the 197s, there were ABBA bands, and in the 198s, there were Roxette bands. In 1994, the band "Ace of base", which quickly became popular, pushed Swedish pop music to another peak.

The band "Base Experts" is composed of Jonas Berggers and his friend ULF Ekberg, with Bergers' two sisters Jenny and Malin in the choir as the lead singers. This four-person group from Gothenburg, a famous Swedish city, did not develop smoothly at first. However, after turning to Denmark for development, they achieved quite good results with a song "Wheel of Fortune". After that, they successively released a series of singles such as All That She Wants, Happy Nation and The Sign, which were widely welcomed: Ace of Base soon became a very popular band. In 1994, an American company released their debut album The Sign. When the album was released in Europe, it was named Happy Nation. This album and its single "Everything She Wants" quickly won the charts respectively, and Ace of Base became the first Swedish band to win the Billboard charts in the United States. The single "Symbol" became one of the best-selling singles in the United States in 1994, and won the championship in the charts of eight countries. "Everything She Wants" ranked first in the charts of ten countries and was hailed as the most successful single in Europe in the past ten years (1984-1994). And "Happy Garden" has also won the championship in the rankings of seven countries.

Ace of Base band won two Billboard music awards in 1994 and three world music awards in 1994/95. "Symbol" has sold more than 2 million copies, creating a Guinness World Record for "the most successful and best-selling debut album in the world", and its achievements can be described as impressive. In 1995, Ace of Base released their second album "Bridge". Compared with the previous album, Bridge has obviously broken away from the style of pure reggae and electronic dance music, showing a diversified musical tendency and a more serious mood. This album has been a great success again. At this time, Ace of Base has become a moving myth in Swedish and even world pop music.
