 The Onyx Hotel Tour to promote In the Zone was the fourth concert tour by Britney Spears . 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 phrase ' in the zone ' . 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 . The tour was divided into seven segments : Check @-@ In , Mystic Lounge , Mystic Garden , The Onyx Zone , Security Cameras , Club and the encore . Check @-@ In displayed performances with dance and advanced in the hotel theme . Mystic Lounge featured an homage to Cabaret and other musicals , while remixing some of Spears 's early hits . Mystic Garden displayed a jungle @-@ inspired stage . The Onyx Zone displayed a ballad performance with acrobats . Security Cameras was the raciest part of the show , with Spears and her dancers emulating different sexual practices . Club displayed a performance with urban influences . The encore consisted of a system malfunction interlude and Spears performed wearing a red ensemble . The tour received mixed reviews from contemporary critics , who praised it for being an entertaining show while criticizing it for looking " more [ like ] a spectacle than an actual concert " . The Onyx Hotel Tour was commercially successful , grossing $ 34 million . In March , Spears suffered a knee injury onstage which forced her to reschedule two shows . In June , Spears fell and hurt her knee again during a music video shoot . She underwent surgery and the remainder of the tour was cancelled .
