The selection of Kristian follows the theme of the contest this year, Celebrate Diversity, since his father is Bulgarian and his mother is from Kazakhstan. He started his musical journey at the age of 6. After going solo when he was 11 years old, he took part in many competitions, but the first big boost for Kristian’s career was his 2014 appearance on Russia’s The Voice Kids, where he was mentored by for Eurovision Song Contest winner Dima Bilan. Kristian recalled the experience fondly: "Dima is a great guy and he was the one who inspired me to reach the final and give my best week after week. Without him it would have been impossible for me to do it."
In August 2015, Kristian left Russia to take part in Season Four of the X Factor Bulgaria, where he finished as a runner-up. His Bulgarian debut, Ne si za men, was released by his record label Virginia Records, topping the official national airplay chart for two weeks. It was followed by an English version, You Got Me Girl. Kristian's next single, Vdigam Level, was a number one hit for 14 weeks and has now received almost six million views on YouTube.
For most of April Kristian has been on a promotional tour taking in London, Tel Aviv where he was the first artist on the dance floor at the opening reception of Israel Calling. Yonight he will appear at Eurovision in Concert in Amsterdam.
