Enrique Iglesias and Jennifer Lopez taught me a little something Sunday night at the Toyota Center . . . I've wasted my life going to indie shows.

No one ever carries signs saying things like "Dance with me Beach House" or "I want to have your babies Guided by Voices" at indie shows. No one rushes the stage the second a singer gets close to the audience. There's rarely a smoke machine and certainly never a laser show. Ever think of backup dancers, Sonic Youth?

Anyway, people were so excited to see Enrique, who kicked off the evening, that many fans attached LED lights to their signs so they could be read in the dark. Kind of genius, really.

After showing an ad for Atlantico Rum, a liquor he's promoting, Iglesias started his set with clubby 2010 hit "Tonight (I'm Loving You)," which morphed into its more awkwardly-titled version "Tonight (I'm Fucking You)" by the end of the song.

Blasts of steams and some simple pyrotechnics kept the excitement high as he transitioned to thumping jams like "I Like How It Feels" and "Dirty Dancer."

A mid-tempo song in Spanish led to an impressive rendition of "Bailamos" — which I just learned was originally from Will Smith's bizarre late-1990s film Wild Wild West — before an unsuspecting young man named Robin was called to the stage to help sing the Ben E. King oldie "Stand by Me." Nervous at first, Robin ended up belting out the lyrics like he was the headliner.

Surely, the shots of Atlantico Rum Iglesias poured into his mouth helped.

Robin's guest performance was one of the highlights of the night until Iglesias brought a very pregnant Roula from KBRE's Roula & Ryan morning show onstage for his chart-topping 2001 ballad "Hero." Knowing no limitations when it comes to entertainment, Enrique kissed her on the lips . . . and then on her stomach.

No indie rocker in his or her right mind could've pulled that off.

Jennifer Lopez: Icon

After Iglesias closed his show in a plume of white confetti, the crowd waited patiently as the roadies changed sets and Jennifer Lopez quite literally sprung onto the stage (through a trapdoor) for a classic Hollywood top-hat-and-cane routine with her dancers. While admittedly a little odd at first, the number helped remind us all of JLo's palpable A-list star power.

Whereas the personable Enrique worked the crowd with his casual charm and catchy songs, Lopez was focused on an athletic array of tightly-orchestrated dances that matched the cool intensity of her two opening tracks, "Get Right" and "Love Don't Cost a Thing."

The Lil' Wayne collaboration "I'm into You," complete with some psychedelic graphics of Aztec ruins, was up next as she moved into the early dance single "Waiting for Tonight." As JLo worked her way across the stage, she would stop in front of these concealed air machines that majestically blew back her hair.

Following a sequence of hits with a choreography — and bicycle shorts — harkening back to Lopez's time as a Fly Girl on In Living Color, she took a moment to pay tribute to Tejano legend Selena, who Lopez played in the 1997 independent film about the singer's life.

The biggest surprise came during the encore, when Lopez's twentysomething boyfriend Casper Smart came onstage to dance and pull off a few back flips.
