Niall Horan has come into his own as a singer and songwriter, blending folk harmonies into his pop sound to create the No. 1 album "Flicker", featuring the massive hit single "Slow Hands." Horan is hitting the road for his "Flicker" World Tour 2018, and he'll be making a stop at the Northwell Health at Jones Beach Theater in Wantagh, where he'll rock out to new songs and old faves, with rising country-pop star Maren Morris ("The Middle," "My Church") as the opener.
