Those Darlins are tough. Life on the road has worn Nikki, Jessi, and Kelley Darlin down, but they've kept on keeping on. This Tuesday, they make their way to the Zoo Bar, and you might find yourself there, too, for free if you play your smarts just right.

See how tough the Tennessee group is in the video for the song "Be Your Bro." And win tickets to Those Darlins' show with The Killigans this Tuesday at the Zoo Bar by answering the trivia question below.

Before we ask you how well you know your Lincoln concert history, we want to be clear that we require one thing of you to win a pair of tickets: You must be registered to Hear Nebraska. Anonymous answers won't be considered.

That wasn't so tough, was it? No, be the first to answer the following question correctly, and the tickets are yours:

Q: Those Darlins' first Lincoln appearance was at last year's Lincoln Calling. Where did they play and with whom?

Let's hope you're getting lucky with this one. And stay tuned for a Hear Nebraska interview with Those Darlins early next week.
