Anais Nin is interesting, if not really as engaging as De Staat is supposed to be, with all the constant breaks stopping you from ever getting a nice sense of the music's flow for much of the piece. While I cannot compare recordings of that, this recording of De Staat is the most dull thing I've heard in ages. Such is due to Atherton's horribly lethargic tempos, which take away so much drama from the music it is hard to believe it is the same piece. The unmusical breaths everywhere are made obvious on this recording, and the oboes use a vibrato that is on examination is quite questionable. He wanted this music to be entirely free of vibrato in the singers, so I'd assume he'd say the same of the oboes.
If you get this disc, skip De Staat and you should be fine. I'd recommend instead either Reinbert de Leeuw's recording or the Nederlands Blazers Ensemble recording on their personal label (if it ever goes back in print).
