Luc Arbogast sits outside French cathedrals (sometimes inside) and sings medieval songs in a pure and resonant counter-tenor. It's a wonderful voice. Also he shaves his head and wears tattoos. I tried getting onto his MySpace site and it screwed with my computer, so I wouldn't recommend you going there, but really there's no need because there are recordings and videos- plenty of them- on YouTube. He looks like a biker and sings like an angel and he has my favourite song of all time- Walther von der Vogelweide's Palastinalied- in his repertoire.
