The X Tour (Christina Aguilera)

Aguilera had last toured in Europe in 2006 with her Back to Basics Tour, with the X Tour marking her first the arena tour of the continent in twelve years.[5][6] In March 2019 it was revealed that one of the cities the singer would visit will be Stuttgart.[7] On June 26, 2019 it was announced that a New Zealand quartet Drax Project would open for Aguilera during her European concert tour.[8]

A second date was added at the SSE Arena in London, due to high demand.[9]

The tour received strong critical praise. Katie Hawthorne of The Guardian opined that "this dazzling spectacle feels almost like a one-woman variety show, were it not for the eight dancers, three singers, full band and mountain of glitter". She complimented Aguilera's voice, calling it "genuinely jaw-dropping", "rich", and "powerful".[10] Una Mullally, an editor of The Irish Times, noted that "as Aguilera explodes on to the stage, her current energy is as fierce as her past legacy".[11] Tim Heap, writing for the gay-themed magazine Attitude, commended on the show's setlist: "For every high-energy banger, from a reworked 'Genie in a Bottle' to a 'Candyman'/'I Want Candy' mash-up, there’s a ballad that really lets the vocals soar". He gave the tour a four stars rating, and added: "It’s not always easy to be a fan of Xtina, but when live performances are this good, it’s worth it".[12] Katie Fitzpatrick from Manchester Evening News wrote that, "From the punchy pop of 'Ain’t No Other Man' to the bugle bop on 'Candyman', this is a flawless and full-throttle journey through Aguilera's career—and the costumes are fabulous".[13] She also noted that The X Tour "delivers the razzmatazz" of the singer's Las Vegas residency.[13] Helsingin Sanomat's Anton Vanha-Majamaa provided a positive review, and praised the tour for its feminist statements, intense theatricality, and rich choreography.[14] He called Aguilera "one of the most important stars on the pop music scene".[14]

Metro's reviewer Rishma Dosani, who attended the show at Wembley Arena, praised Aguilera for her emotional performance of "Beautiful".[15] Writing for Express & Star, Kirsten Rawlins stated that The X Tour was "a beautiful show from start to end, filled with messages of self-love, peace, and female empowerment—mixed in with smoulderingly sexy costumes and dance moves."[16] She also called Aguilera an artist of "exceptional talent, power, and humanity".[16]
