From Wikipedia:
"Water" is a song by Elitsa Todorova & Stoyan Yankoulov which represents Bulgaria and opened the Eurovision Song Contest on 10th May, 2007. The song has drum beats, and two percussionists sing and play their percussion instruments at the same time. Elitsa's deep-toned voice is telling the dramatic story of Bulgarian folklore.
The singers explain the title: "Our folklore is like water. We've chosen this title "Water", because in Bulgarian folklore there are very slow beautiful songs, which are like a lake. But we also have songs, with very fast rhythm which are like a waterfall. And my wish is this song to be like "Water", a gasp of fresh air, for the human spirit and soul. When we recorded the promo video of this song, they poured lots of rain on us, and I felt purified. I want everyone, who hears this song to feel the same way - liberated. This is a very positive song! I'm sure that people will feel it!"
