If you liked Schickele's Oedipus Tex, then you've heard pretty much all the ideas used in the Blugrass Cantata before. This recording, however, has an impenetrable libretto sung in German, with no translation in the cover notes. It's also sung mostly by Peter Schickele, whose voice is dull, flat, and less than melodic.The No-No Nonette is also less than inspired.All in all, a great disappointment. Buy Oedipus Tex, it's hilarious and very clever. Leave this one on the shelf.
