The Road

The remaining 11 musicians board the tour bus bound for Dallas, where the crowds are bigger and the stakes are higher; split into two groups, they'll open for Keith Urban across two nights at The Factory, performing both covers and original songs.

The second group of musicians take the stage as they battle it out during another night of dynamic and emotional performances; the musicians give an inside look into how they choose original and cover songs.

The tour comes to Oklahoma for two shows. Gretchen Wilson kicks off show one, putting pressure on the four musicians who have to follow her.

The pressure mounts for the five musicians performing in the second show as one more singer must leave the tour.

The tour bus rolls into Tulsa, Oklahoma, for a concert at the iconic Cain's Ballroom; country artist Dustin Lynch sits in with Keith Urban; the seven musicians are divided up to perform two group covers before performing their originals.
