The first contestant to take the stage was Magdalena Tul from Poland who gave a smashing performance.
That rehearsal was of course followed by a series of other wonderful first tries on the stage of this year's Europe's favourite TV-show by contestants from Norway, Albania, Armenia, Turkey, Serbia, Russia, Switzerland, Georgia and Finland.
Tommorrow the second half of the first Semi-Final participants will get their first try. It'll be the artists from Malta, San Marino, Croatia, Iceland, Hungary, Portugal, Lithuania, Azerbaijan and Greece this time.
