A source close to the situation explained:
What really stood out, aside from the radio-friendly melody, was that Kiesza really seems to be an entertainer. She didn't just stand on stage and sing her song. She had a fully-choreographed routine that not only brought her into the audience, but brought her outside to dance on the streets as well.
The Canadian singer, pronounced kai-zuh if you were also confused on how to differentiate between her and Kesha, was on The Late Show as part of her press circuit ever since her music video for Hideaway went viral.
But Hideaway isn't just her first single, it's also the name of her EP, which came out this week!
Ch-ch-check it out (above)!
