A few months ago I mentioned the creepy, ethereal joy that is Fovea Hex. Not only do they have a new album coming out soon-ish, but I just found this wonderful clip of a live performance.
Belaying their super-seriousness, Clodagh Simonds starts by singing "Somebody unplugged my laptop," which is why they crack up a bit at the beginning. But it quickly comes together again and they perform "Don't These Windows Open."
I assume the other vocalists are Laura Sheeran and Lydia Sasse, with Cora Venus Lunny on cello...but I don't know for sure.
