The Black Eyed Peas' 'I Gotta Feeling' is an anthem often heard bellowing from the speakers at sports stadiums across the country. At Super Bowl XLV, the Peas fittingly opened (and closed) their halftime set with the 2009 summer hit. The Peas were all cloaked uniformly in futuristic, studded black leather attire and performed on the circular stage, surrounded by dancers one level below the stage and dressed entirely in white ... Until said white outfits started to glow in the dark. sported a head piece that looked like some sort of helmet/doo-rag hybrid made of industrial-strength, clear tape.

Next up in the wow factor medley was 'Boom Boom Pow,' followed by Guns N' Roses guitarist Slash. Dressed in an outfit similar to the Peas, the guitarist rose from under the stage while belting out the hallmark riff to 'Sweet Child O' Mine.' Fergie, who collaborated with the guitarist on his self-titled solo effort last year, took over the vocals normally reserved for W. Axl Rose. We loved seeing Slash's signature top hat bedazzled with metal studs.

The Peas' set was high octane, with a little bit of 'Pump It' and their Grammy-winning single, 'Let's Get It Started' thrown into the mix. That's when Usher showed up, draped in one of those futuristic white get ups and mirrored sunglasses while singing 'OMG.' During 'Where is the Love?,' the dancers' suits glowed a fiery shade of red.

The Peas' 'The Time (Dirty Bit)' -- which samples the 'Dirty Dancing' '80s hit '(Now I've Had) The Time of My Life' -- made it into the set before things came full circle and the group ended with another bar of 'I Gotta Feeling,' accompanied with dancers who looked like they were wearing boxes on their heads.

It was a literally electric, wow-inducing and utterly futuristic spectacle courtesy of, Fergie and co.
