ALEXCALIBUR (Alex Gulla) has an incredible voice – rich, supple, and flexible – and his live show is nothing short of mind-blowing. Note: that link may or may not be NSFW, depending on where you work, and contains pictures of Mr. Gulla singing while wearing very small trunks and not a lot else.
I chose this particular song because I find it incredibly soothing, and the video, created by Gulla and Katie Torn, is illustrative of his general aesthetic. You can listen to more of his work here.
