One of the most anticipated rehearsals of today has to be Bulgaria as they are second in the odds to win the contest. It took us a long time to get to see anything from this rehearsal, and it was less than a minute.
Luckily we got to see it in full as well. He starts standing on a dark stage with some hand choreography. Lots of flashes and sparkling lines / holograms that seem to come from where he stands. They have some interesting visual effects but there are also some visuals that don't come across so well to me, like the fasting moving screens where the image of Kristian kind of 'jumps' from one corner to another, and later the rushed images that seem like fast forward. What I don't know if those visuals are actually there or just the way we see it in the press centre.
Vocally Kristian did well, but I think there's still a lot of work to do for him to live up to the high expectations.
