Monday afternoon, Jack White unceremoniously sauntered through the crowd at Hollywood Candy in the Old Market. The shy musician smiled once and shook a few hands.

White wasn’t there for sweets. He was there to rock out.

Less than an hour before he arrived, his record label posted a message to Twitter that the rock star would play a small, free, secret show at the combined candy and antique store in the Old Market.

Within half an hour, the store was flooded with hundreds of people and a line wound through the aisles.

Casey Boyd, 32, traveled from Moline, Ill., to see White’s Monday night performance at the Omaha Music Hall.

“We were about to get in line when we heard about it on Twitter, so we rushed over,” she said.

About 100 people fit into the store’s tiny movie theater to watch White and his six-member, all-female band play six songs.
