Review in All Music of “Waiting for the Barbarians”:

“…coming through Glass’ own label, this is in every way satisfactory in
communicating this major Glass effort, one that rightly he should be
very proud of — it’s a real achievement.”

A friend of mine showed me the June issue of SPIN Magazine last night which had a 4 page feature on Philip Glass.  In the article, in announced a release of a 10-disc retrospective boxed set to be released on Nonesuch this year.  There is no mention of it on the Nonesuch website, and I cannot access the SPIN article.
