Singer, songwriter, and multi-instrumentalist Niall Horan has taken the world by storm. A former member of One Direction, known as one of the best-selling boy bands of all time, he has toured the world and played to millions of fans in sold-out stadiums worldwide, including Wembley Arena. Niall is a storyteller at heart. His two solo albums Heartbreak Weather and 2017’s Flicker, released on Capitol Records, were critically acclaimed. The latter debuted at No. 1 on the Billboard 200 in the US and produced the hit singles “This Town” and “Slow Hands.” Niall’s emotive voice is rich and insightful, as he effortlessly captures his real-life experiences and range of emotions. The result is a whirlwind of modern pop and nostalgic grooves. As fans are eagerly awaiting his next solo project, Niall has also just been announced as the newest coach for next season of The Voice USA.
