I've come late in the game, and can't help but wonder what it was like for those who got here early and heard it piece by piece. I can say it's wonderful to read straight through the sections you have so far. It's extremely powerful, and the movement of rhythm from section to section and the use of rhyme is very effective.
Also, taking aside your writing voice, you have a nice speaking voice. I was half afraid to click on the sound link in case you didn't -- and I didn't do it until I'd read the entire poem a couple of times. It's terrible of me, but I'm sensitive to voices and though it's a wonderful thing to hear poetry read aloud, it ruins it for me when the unfortunate poet is cursed with a squeaky whine. Color me shallow if you must.
(And now I'll go back and read all the comments, which I don't like to do until I've commented myself!)
A few things that particularly struck me:
and learned like
any animal learns—
ears nipped and angry
-- tells us so much about Jacob in a single image
Jacob's sweat dripped
and beaded into mudpie
buttons in the dust.
-- I love, love, love this image.
and a boy alone
cleaved to the skull of a dog.
-- nice. very nice
Dirt has a way
of swallowing tears
-- A lovely echo of the mudpie button image I liked so much.
The way you used rhyme in "The Interview" was particularly effective for me. And you've done a wonderful job of capturing the jeers in their voices.
Her lips the color of turnips
fixed on words that referred to grace.
I like the image and your choice of "referred" ("fixed," too, actually.)
Thus an orphan was delivered
from a wicked life of sloth
and processed into bondage to
a creature of the cloth.
I like the use of rhyme and the irony.
for it was by the hand of God
that the strap was swung.
-- nice.
The Wretched Sing the Song God Wants to Hear
-- love the title of this section.
But Jacob's was the prayer
of the mockingbird.
--Harper Lee would approve.
whose thorns
like concertina wire
guarded the
forest edge.
-- wonderful image.
as Jacob salted his lips
at her cheek.
-- I like this a lot.
