It's more a track-by-track description than a "proper" review, but "A Discreet History of Bone" is discussed at Mark Coyle's Unbroken Circle blog. Here's what he says, and while you're at it, you should check out his web site.

With its plague depiction cover 'A Discreet [sic.] History of Bone' arrives by Anvil Salute. This release is a group improvisation performed live in April this year. It starts very hushed, almost imperceptible with cymbal washes, tense but quiet guitar and a feeling of huge space. On the second piece 'Blinking Red Face, Little Waxed Moustache' there is an emphasis on individual sounds rather than instruments making it seem like a field recording rather than music. 'Variations on a Modal Theme' is excellent, a soft unresolved melody explored on guitars and xylophone. 'Jive Talking' has faux voodoo rhythms, pounding with marimba. On the final extended piece 'Brad Is All; We All Play Free' we have an experimental jazz style close to A.M.M.. Screeching wind instruments play around a tense drone and chaotic percussion and then once this section is done, we end on a lovely quiet section.
