After ten years and numerous albums, the band broke up in 1997. When the main singer Enrique Bunbury went solo, other members of the band also found a different musical path in life. In 2007, as part of a 20-year anniversary celebration and 10 years after their break-up, they organized a 10-concert world tour.
