The first country act to play two straight nights at the iWireless Center may have left some remnants of the building for tonight's audience.

But Jason Aldean's opening show on Saturday night was an old-fashioned barn burner, rattling the rafters and keeping everyone in the sold-out arena rapt at attention.

In his third time headlining in Moline, Aldean threw a few curveballs, but he kept fans singing along and in motion from the SRO front pit to the nosebleed seats.

On the latter part of his "Night Train Tour," a group of six rotating and moveable video monitors — the best technical aspect of the night — showed approaching steam engines, with a silhouette of the singer appearing on the rear video leading to his entrance for the song "Crazy Town."

The singer cruised through his 8 1/2 years that have produced 19 country hits (all but the sentimental "Laughed Until We Cried," which didn't fit the party-all-night vibe Aldean was going for) during a 90-minute set.

Aldean didn't have much to say from the stage except a few choice remarks about the Midwest temperatures and snow.

"Where I'm from, they close down schools for three weeks when this happens," the Georgia native said.

Backed by a solid five-piece band, many of whom have been with the singer since before his first record contract, nearly every song in the 20-some tunes set ended with the same pattern: very abruptly, with the lights going down for a few seconds and then back up for the next song.

Pulling a page from Brad Paisley's act last year, Aldean had a virtual duet with his "Don't You Wanna Stay" partner, Kelly Clarkson, in a crisp and convincing video that made a few in the audience believe the female singer had actually stepped onto the stage.

Filling in for Luke Bryan and Eric Church on Aldean's 2012 collaboration, "The Only Way I Know," the singer was joined by Tyler Hubbard and Brian Kelley of Florida Georgia Line, whose 45-minute set warmed up the crowd.

The duo took the stage with all of the confidence and bravado of the headliners they'll soon become.

FGL's set owed as much to rock and hip-hop as it did to country.

Besides their own hits and a few cuts from their debut album, they covered Alabama's "I'm in a Hurry" and Bruno Mars' "Grenade."

The two, especially Hubbard, overflowed with a charismatic stage presence that shows they may be more than the flavor of the month.

Their time onstage closed with "Cruise," the duo's first No. 1 song, the most-played country song of the year and, according to music websites, the most downloaded song in the genre.

"You guys have forever changed country music history," Hubbard told the crowd in thanking them for their support.

Tyler Farr, a 29-year-old Missourian who was first noticed last year thanks to the No. 1 song "Redneck Crazy," opened the show with a 15-minute set. Comfortable on an arena stage, Farr seems to have already mastered, like the two acts later in the night, the right way to work a crowd.
