Once again, we have a suggestion from or readers. Ola Sletvold, who has already suggested two other contraltos, has pointed me in the direction of yet another fabulous singer.
Aafje Heynes is a Dutch contralto, who focused manily in the concert and oratorio areas of performance, with a key interest in Mahler. Indeed, her perfromance of Mahler's Second Symphony is regarded as a classic.
Below is a video of her performing one of my favourite contralto pieces, the haunting Dank, sei dir Herr attributed to G. F. handel.
Enjoy!
