[5] The tour was described as an "all new production, costumes and stage design creating a visual and audio event with the once in a lifetime excitement her fans around the world have come to expect from one of the brightest stars in music today.

"[5][6] During an interview with Ryan Seacrest after she performed "California King Bed" on American Idol April 14, 2011, the singer spoke about the tour's development.

[5] Rihanna spoke about Green joining her on tour in a press statement, saying "I'm a huge fan of Cee Lo since his days with Goodie Mob and with Gnarls Barkley.

The next song, "Disturbia", follows with Rihanna taking off the blue dress and dancing around in a colorful daisy duke, leading into "Shut Up and Drive" where a car covered in graffiti is present in the middle of the stage.

The second segment begins with a cover of Prince's "Darling Nikki" where Rihanna, dressed in a suit and holding a cane, rubs against her female dancers.

Rihanna returns to the stage atop a pink tank shooting puffs of smoke, with her and her dancers dressed in military gear, to perform "Raining Men".

The second video interlude features Rihanna wearing a red dress while waving sheets of chiffon in the air and ends with the spoken line: "I hate that I love you."

Rihanna returns to the stage wearing a bright yellow dress in brown thigh high boots to perform "Unfaithful" on a platform behind purple neon bars.

"[16] Bernard Perusse of the Montreal Gazette stated that the tour was a visual spectacle saying, "Pods, dry ice, sparklers, plumes of smoke, a platform raising her from below stage and back down when needed, a moving section of the floor to convey her from one side of the stage to another, videos, writhing dancers, a cannon, arena-rock guitar solos, umpteen costume changes and maybe a record for the amount of times a performer has screamed 'Montreal!'

"[18] Amanda Ash of the Vancouver Sun stated, "Rihanna knows how to throw a party -a sexy, steamy, tight and-bright bash where yesterday's troubles are crushed beneath mile-high stilettos and drowned by intoxicating club beats", and added, "Rihanna turned Rogers Arena into a giant dance club on Friday night.

From the endless hits including 'S&M', 'Man Down', 'Hard', 'Pon De Replay' and 'Unfaithful'; the spectacular stage and props to her playing a solo piece on drums, the girl who grew up in nearby Westbury Road was awesome.

14,000, mostly female, fans enjoyed the set which kicked off at 9.15pm when the singer emerged to thunderous sound effects and a "blitzkreig" [sic] of video from a silver shell wearing a luminous blue jacket.

"[21] Scottish tabloid Daily Record remarked, "R&B superstar Rihanna blew the roof off Glasgow's SECC last night with her aptly-titled Loud tour.
