(Is it a cover if it rearranges the original piece? I don't know. W/e! Soundcloud refused to process the track this morning so I have to try again later - either way, I was going to post this here.)
This is the audio half of a fan tribute made by yours truly. I will be cobbling together a YouTube video that contains the other half.
For anybody who wasn't around for LoZ: Majora's Mask, this is the Song of Healing. I transcribed it, hand-corrected notes, and then added my own choice of articulations before finally re-arranging the entire piece in the second half.
