I think the setup for JESC 2020 would work perfectly as well for Eurovision. I didn't miss a thing. The smaller stage in the studio allows for more intimate effects with the visualization than the big stage. As in recent years, succesful acts, tried to make the stage smaller for their impression, such as Mans, Sergej, Michael Schulte. I wouldn't mind Eurovision from the studio with awesome effects. It would make it more affordable for all delegations, especially in regards of the economic depression we are headed, and it would level the playing field for all countries to host the contest. Even San Marino could do it, which also means for me, Andorra, Monaco, Luxembourg, Slovakia might be motivated to return and we could see all 48 countries compete in a year.
I think Kazakhstan would have failed to impress on a big stage, but is the prime example for an amazing act in the studio stage. The close backdrop was essential for the induction of personal tears on my behalf.
