The Onyx Hotel Tour was the fifth
concert tour by American recording artist
Britney Spears. It showcased her fourth studio album,
In the Zone (2003) and visited North America and Europe. A tour to promote the album was announced in December 2003. Its original name was the In the Zone Tour, but Spears was sued for trademark infringement and banned from using the name. Spears felt inspired to create a show with a hotel theme which she later mixed with the concept of an onyx stone. The stage, inspired by
Broadway musicals, was less elaborate than her previous tours. The setlist was composed mostly by songs from
In the Zone as well as some of her past songs reworked with different elements of jazz, blues and Latin percussion. Tour promoter
Clear Channel Entertainment marketed the tour to a more adult audience than her previous shows while sponsor
MTV highly promoted the tour on TV shows and the network's website.
