In 1998 Los Planetas released “Una semana en el motor de un autobús”, the most important album published by an indie band, one of the best pop albums in Spanish and a classic work that created the myth that still exists. “Una semana en el motor de un autobús” managed to awaken passions in the specialized press from the beginning and was named best national record of 1998, second best national record of the decade of the 90's and 18th best national record of the twentieth century.
Los Planetas, together with a group of composers-arrangers specialized in orchestration, have adapted the complete album to be able to interpret it with a symphonic orchestra and a chorus.
