Michael - Christian - Peter Paumgarten, Uli Staber
Apparently the first three have the same last name, though I can't swear to that. Brothers? It's interesting to hear this music sung by a quartet instead of the typical choral performance. From what I've read Schubert would have been more likely to have conceived of it as sung by such a quartet than a large chorus. Though I believe such choruses were known to him.
Here it is sung by another quartet:
It's a nice, gloomy song for what is a cold, wet Thursday night, here.
