It's something like the nephew of Pierrot Lunaire. I've only just started listening to it, so what I say about it won't make much sense yet. But it's a setting of poetry (by René Char) and it's a chamber piece. And it has Sprechstimme, which Schoenberg devised for Pierrot Lunaire.
The red caravan on the edge of the nail
And corpse in the basket
And plowhorses in the horseshoe
I dream my head on the point of my knife is Peru.
