Has anyone reading this know anything about a poet named Edward Esch? The Cathedral Choral Society is performing a choral setting of a Latin translation of one of his poems, and the woman who prepares our program notes has had no luck finding information about him. He's not in the Library of Congress catalogue, and a Google search turns up only references to the choral work we're performing. Let me know if you know anything about him.

Here's the poem:

Light,
warm and heavy as pure gold
and the angels sing softly
to the new-born baby.

ETA: mrghoul cleverly suggests contacting Eric Whitacre, the composer of the choral work based on Esch's poem. (The title of the song is Lux Aurumque, by the way.) It's an excellent idea, but the annotator has already been in touch with him, and he had no information about the poet.

Another potential clue is that the poem is printed in the sheet music without a copyright statement, which suggests that the publisher believes it to be in the public domain. I suggested to the annotator that she contact the publisher for information, but I haven't heard back from her.
