For me one of the coolest things about the show is .Everyone he had open for him are his friends , one of the guys his dad took zac in at an early age , another is actually part of his band but also has his own . He had them play on stage with him through at least 4-5 songs . So it wasn't a cool thanks for opening now get off the stage . Branched out of just country , when he did metallica like 3-4,000 people were singing at the same time , gave me chills .
