Don't kick yourself too hard for thinking Girl Talk would be a flash in the pan. Gregg Gillis thought so, too.

Don't kick yourself too hard for thinking Girl Talk would be a flash in the pan. Gregg Gillis thought so, too.

"I didn't expect that to last," Gillis said in a phone interview last month. "I understand how fickle certain styles of music fans are."

Gillis had been making experimental music for six years before "Night Ripper," his third album as Girl Talk, raised the bar for monster mashups in 2006. He held on to his day job as a biomedical engineer and flew out of Pittsburgh on weekends to host raging dance parties.

Fans would climb on stage to grind around Gillis as he shed layers of clothing, flailed wildly and hurried back to his laptop to edit beats. It was the ultimate expression of the social media era: audience as show, dancing to a monolithic jumble of repurposed pop samples.

Girl Talk was a phenomenon, but surely not one with legs?

"When people were kind of skeptical of it, it kind of motivated me," Gillis said.

He responded by quitting his day job, delivering two more smash albums and exploding his live show beyond its glorified house party motif.

Per Girl Talk tradition, latest platter "All Day" is bursting with pop music samples. Its endless stream of "Remember that?" wags a fair-use finger in the face of copyright law, Dikembe Mutombo style. It was released online for free, a tactic Gillis said coincided with a spike in ticket sales.

"All Day" lets Gillis' source material breathe a bit more than his former rapid-fire deployment. Black Sabbath's "War Pigs" gets an extended Ludacris makeover. Terror Squad's macho "Lean Back" crosses streams with Spacehog's epic alt-rock hit "In the Meantime." MOP's "Ante Up" syncs seamlessly with "Party in the USA."

One of the tracks is called "Jump on Stage," though that's becoming harder to do at Girl Talk shows, at least in the spontaneous manner of old. Gillis is playing bigger venues with more security. Letting people storm the gates was resulting in too many technical disasters as the stage show got more elaborate.

"With this tour it's the first time I've actually had a crew and a set design," Gillis said. "Prior to this tour, it's always been me traveling with a couple friends."

Before the jaunt that hits LC Pavilion on Thursday, Gillis was already incorporating handmade props - balloons, confetti, leaf blowers shooting toilet paper - though those elements were absent from a pair of 2009 shows at Newport Music Hall. He's excited for Columbus to experience the next evolution of Girl Talk.

Who knows? Next time he might be playing an arena.

"I think at any given moment with this whole project, it's hard to tell where it can go," Gillis said.
