Aguilera's show on June 25, at the festival in Marcolla marked the first time she performed in Spain in almost twenty years, since her performance in Barcelona on The Stripped Tour in 2003.

Reception
The set garnered critical acclaim. Writing for The Guardian, Dave Simpson gave the opening night of the second leg in Scarborough show four stars, calling it "an 80-minute audiovisual extravaganza" and complimenting the wide range of genres included and the "dazzling effect" of her voice. Elle May Rice of the Liverpool Echo gave the show at the M&S Bank Arena in Liverpool a five star rating, complimenting its costuming, versatility and Aguilera's ability to keep "the crowd captivated to the last second". The Mancunion's Jay Darcy called Aguilera's performance an "electrifying showcase of her artistry and success", and complimented the show's "dazzling and dramatic" nature. In a four star review for i, Alim Kheraj called the London set at The O2 Arena "worthy of her pop legend status", calling Aguilera "a born show woman" and praising her "chest-tightening" vocals. However, Kheraj went on to criticize the minimal staging and "muddled" sound production, giving credit to Aguilera's catalogue and stripped vocals for carrying the show. Another four-star review came from Stephen Dalton of The Times. Dalton praised Aguilera for her vocal abilities, writing: "her baroque, hyperbolic, melismatic vocal technique is the real genie in the bottle here".
