Prior to the announcement Czech TV played a trick on Mikolas, announcing that he had finished second in the national selection:
Mikolas Josef is a composer, producer, singer, multi-instrumentalist and director of music videos and grew up in Prague and Znojmo. He now lives mainly in Vienna. He comes from a musical family and has been playing the guitar since he was five.
Mikolas graduated from The English College in Prague, and although his study grades were good enough for him to go on to prestigious UK Colleges, he opted not to keep studying, but to get on with his musical career.
Martina Bárta represented the Czech Republic at Eurovision 2017 with the song My Turn.
