Pop diva Christina Aguilera's new road trip might be called Back To Basics -- after her 2006 double album of the same name that's inspired by vintage jazz, soul and blues -- but, quite frankly, it sounds like anything but.

When she plays the Air Canada Centre tonight, the 27-year singer will make 10 costume changes, have 20 dancers and musicians, 600 moving lights, 820 pounds of confetti, and one carousel horse. And that's just the tip of the iceberg.

Aguilera says if she didn't put on a big production, she'd feel like she was ripping off her fans. "I don't think it would be fair to my audience to just kind of sit on the stage with a mic, if I play an arena and a venue like that," Aguilera said in a recent teleconference interview with North American music writers.

"I want my audience to be able to look around and enjoy a show from all aspects. You know, for me, whenever I go to see a concert, I really enjoy being taken out of my element for a moment and really being able to use my imagination and enter this whole different world. And we do bring sort of a larger-than-life feel to this, you know, old concept."

Aguilera says her Back To Basics staging has elements of big band-halls, juke joints, churches and the circus in order to take concertgoers on a real journey.

After completing the European leg just before Christmas -- the North American leg began Feb. 20 in Houston -- she said she just wanted to enjoy herself.

"It's the most fun I've ever had (on stage) with a show of my own," Aguilera said. "I'm just so excited every night to get out there in front of my audience ... to bring my album to life."

Aguilera, who has sold more than 25 million albums and last month picked up her second Grammy Award, said it was refreshing to reinvent some of her older material for the Back To Basics setlist.

Among them: What A Girl Wants from her 1999 teen-driven, dance-pop, self-titled debut album. That huge hit gets an old-school reggae twist.

Aguilera is a fan of reinvention in terms of image and music, which got a major jolt with her for-adults-only, gritty second album -- 2002's Stripped, which included the singles Dirrty and Beautiful.

For some, the switch from the former clean-cut Mickey Mouse Club member to "Xtina" -- the gyrating, red-leather-bikini-topped, chaps-wearing fighter in the raunchy Dirrty video -- was too much.

"I always just do what I feel," Aguilera said. "With my first album, I kind of had to play by the rules. I came out during the huge sort of pop explosion and that was kind of what I had to do to kind of earn some credit and some respect for myself. A few million records sold later, I was able to do what I wanted to do with Stripped ... It was the first time that I felt that I could really be myself and write my own material and express myself as the woman that I'd grown into at that point. So, that's why that record was necessary for me."
