To commemorate the fifteen years of Enigma, a limited-edition album called 15 Years After was launched, which was the size of an LP vinyl disk, with Leonardo da Vinci's art in the cover, a big booklet with extra art, and featured eight compact discs: all the previous albums, the DVD "Remember the Future", and a special and exclusive bonus CD, "The Dusted Variations", which included Chill-out versions of several of the project's greatest hits. All of the songs are different from the originals and use minimal percussion. This disc also contained the single version of "Hello and Welcome", which was later released as a single. On 28 August 2005, Enigma's management Crocodile Music announced the release of "Hello and Welcome" as a single. It was released in Germany on 10 March 2006.
