Troy University’s pop music ensemble, POPulus, will premiere a new single at a concert Wednesday night in the Janice Hawkins Cultural Arts Park Amphitheater.

The song shares its title with the concert — “Rebuild the Wall” — and is a driving sports anthem inspired by the new wave of excitement surrounding Trojan athletes.

The free concert, a pep rally-style event aimed at supporting Trojan Athletics, is open to the public and starts at 8:30 p.m.

“Rebuild the Wall” is written by Robert W. Smith, who also composed the school’s Alma Mater, and features the music and voices of POPulus, the Sound of the South and TROY’s Concert Chorale.

The concert marks the first public performance of the single, which will soon be released on iTunes.

“We’ve been really inspired by the success of our Trojan Athletics teams,” said Smith, coordinator of TROY’s music industry program and director of POPulus. “The mantra of our athletics program has been ‘Rebuild the Wall.’ We have written and recorded this brand new tune to honor these amazing athletes and their record-breaking achievements.”
