Also something Celtic-trance like this.
Watching this is amazing, listening to it is just so soothing, and I've watched friends sing like this live and it's like entering another dimension, it's so brilliant, and they've told me they just transcend wherever they are and it's almost mystically therapeutic because they just go on for hours.
It'd work so so well on a stage so intimate as Malmo's, I can see it starting with minimal lighting and just a slow fade as the song goes on, resulting in a massive ending with bright green and white lights. Ugh it'd work so good.
