Theodor Andrei made himself known while participating in the 2017 talent show Vocea României Junior, the Romanian version of The Voice Kids, where he reached the semi-final.

Since then Andrei spoke out about the treatment that he faced working with TVR such as rejecting all the ideas he had for staging for his performance in Liverpool and imposing a slower revamp to his song.

[8] Theodor Andrei took this opportunity to announce his first UK concert in London organised by Platform '96 called Stage 002 on the 28th of July at The Water Rats, a renowned venue steeped in music history with Bob Dylan, The Pogues, and Oasis playing their first gigs.

His set was one hour long and included songs from his album Fragil., Eurovision Medleys, as well as covers from various artists of various genres, such as Frank Sinatra, Eminem, Madcon, Bruno Mars, Måneskin, Olivia Rodrigo, Miley Cyrus, Creedence Clearwater Revival and many more.

Theodor also invited his girlfriend Diana as a special guest to surprise the audience with duos and dance breaks.
