Koe Wetzel and Parker McCollum: Naughty or Nice Tour brings two of country music's most fun voices to Round Rock Amphitheater in Round Rock, just outside Austin. Koe Wetzel brings his rowdy, rock-tinged honky-tonk energy, while Parker McCollum is known for his polished, heartfelt Texas country sound. Together they make a lively pairing built for singing along and staying on your feet. The amphitheater is an open-air venue, so you get a laid-back outdoor setting with plenty of room to move.
