For those of you that haven't heard of Sia, check her out.
Not my normal style of music, but damn she's good.
I'm pretty sure that's the song where for the film clip, she did it all artistically, and she did the whole song in sign language too. (I just re-read that sentence and realized how mangled it sounds
, I meant to say she did the sign language artistically as the film clip)
It's kind of a trippy thought, someone who can no longer (or never could) experience music in the traditional sense, can actually "listen" to that song
