Comments and email from various people prompt me to post a few more versions of Schubert's Erlkoenig.
Here's Marian Anderson, who has a fabulously dark voice for the father, dropping into her contralto range.
Overall, I find Anderson somewhat less dramatic than those singers with more stage experience, and the last line, with the tiny sob, isn't as effective as other singers'.
Here's Ian Bostridge with Julius Drake; a genuinely otherworldly sound for the Erlkoening.
And a bit of a curiosity, Anne-Sofie von Otter with Claudio Abbado and the Chamber Orchestra of Europe; very very dramatic.
