The annual showcase will be held Feb. 27, 2015, at the Nashville Convention Center, where the five acts will close the three-day seminar. While dinner tickets for the performance are sold out, seating-only admission is still available and open to the public on a first-come, first-served basis.

Ballard's current single "Sunshine & Whiskey" just reached No. 1 on Billboard's Country Airplay chart. It follows his previous No. 1 "Helluva Life," which hit No. 1 earlier this year.

Hunt, too, is no stranger to the top of the charts. After writing hits for Keith Urban ("Cop Car") and Kenny Chesney ("Come Over"), he gained his first No. 1 as an artist earlier this fall with his debut single "Leave the Night On."
