Fans packed inside to see the Australian band's show.
The group was named as the "New Artists to Watch in 2012" by Billboard Magazine
Brothers Joel & Luke Smallbone told KTAB they became interested in the music industry at a very young age, thanks to their father, who was a concert promoter.
The duo also said getting on a stage and sending out a message of hope and encouragement through their music is why they do what they do.
After the concert, members of the band signed autographs and posed for pictures with fans.
