I posted the link to Wright's book earlier today on my FB account, and got this great nugget from my Psalms prof, Jack Collins (OT Professor at Covenant Seminary):
The book is pretty decent, but it's short. It's more about motivating us to use the Psalter as a song-book more than we do, and I appreciated that. It covers less than, say, Lewis' Reflections on the Psalms, though it does stick better to the main idea. Wright does articulate a vision for the right kind of interpretation, one that respects the Biblical storyline. Made me realize that the only commentary I know of that carries that vision out is in the ESV Study Bible.Look for a full-length review in Presbyterion early 2014, and if you don't get that journal, I believe it will be accessible via ATLA.
