Gotta admit....that is THE MOST UNUSUAL music form I've ever seen
What amazing LUNGS! Wonder what made them think of doing that? Only part I didn't like was near the end when BOTH ladies started running their hands down the glass. A little too squeaky.
Yeah, I didn't like that same bit.
At the end, I felt like the Elder Gods were about to awaken from the deep!
Their website has info on how they make their instruments, but I haven't found their inspiration.
