Was Wednesday's Lady Gaga concert the most unique mass  spectacle of the year, Denver? Possibly so — considering the  inexplicable costumes, the outrageous energy, the unexpected use of  makeup and the creative spirit that couldn't be tamed.
And that was just the crowd that filled the Pepsi Center.
The star of the Monster Ball, of course, was Lady Gaga, the  well-outfitted pop star who owns America's collective imagination in  2010. Her ultra-stylized stage show didn't disappoint with its creative  garishness, its neon smuttiness, its over-the-top fabulousness.

Gaga was the evening's ringleader in hotpants (and  space-age nun habits and Fever Ray-mutated red gowns). Some of her  vocals were real, and others were augmented by backing singers and a  healthy track. But when you compare Gaga to her peers and predecessors,  this Lady is a legitimate performer.
Cue the piano intro to  "Just Dance" — the hit single that started it all for Gaga, which came  early in the night. Bending over the open hood of a brken-down prop-car,  Gaga's gloved fingers found a piano instead of an engine. Always one to  remind her fans that she can actually play (a la her "Saturday Night  Live" performance from last season), the cameras zoomed in on her  tickling fingers as they led the enrapt arena into one of the biggest  pop songs of the last decade.
"I created (the Monster Ball) so that my fans would have a  place to go — a place where all the freaks are outside," Gaga told the  ravenous crowd. "It doesn't matter who you are or where you come from or  how much money you have in your pocket, because tonight and every night  after you can be whoever you want to be."
Gaga's set included all the jams you'd expect — including  "Paparazzi," "Telephone," "Alejandro" and "Poker Face," which pulled up  the rear of the show. The costumes revolved around themes previously  exploited by Madonna — the sexual, the religious, the strange —
ut Gaga personalized each approach with an admirable flair.
The  Monster Ball's set pieces were urban (a subway car), sexy (a  broken-down car) and supernatural (an enchanted forest) — relatively  muted compared to the tight-fitting costumes that adorned Gaga and her  minions. And they weren't the only ones dressed up.
"Look at all your costumes," she said to the full arena,  smiling, between "Love Game" and "Boys Boys Boys" in the first half of  the show.
Gaga knows spectacle. (A flaming grand piano during  "Speechless?") But she also knows killer pop music. ("Telephone" didn't  need Gaga's partner Beyonce to succeed — and a brassy new song, "You and  I," won over the crowd on first reference.)
And that rare combination makes her the biggest pop star in  the world — a title she could possibly hold on to if she plays her  cards, and manages her poker face,
