something I noticed when rewatching Kiara's performance, this fes they opted for some instruments being part of the backing track with the main difference being the bass, it's more noticeable if you rewatch La+ dark breath from the fes she performed it and the video of the song, in the video they used an 808 and during the fes they used a bass guitar with 0 backing track so it sounded way worse, and in Kiara's performance this year you can hear the 808 so they learned something at least.
