For those who are interested in hearing some alternative (i.e. other) settings of In Darkness Let Me Dwell, here are some decent recordings from the public domain:
Firstly, John Cooper/Copario/Coperario’s 1606 setting of the verse, performed by Helen Atkinson and Din Ghani.
Next up, a rather beautiful rendition of the John Dowland 1610 version of In Darkness Let Me Dwell, sung by Andreas Scholl, accompanied by Edin Karamazow:
Finally, you might enjoy Paint It Black by the Rolling Stones. Please note how very similar the lyrical content is to the verse In Darkness Let Me Dwell, in meaning, albeit not the exact words.
