The soprano soloist was Felicity Palmer, nowadays a mezzo-soprano. It's a pretty fine recording, though I happen to know that Hickox is indeed planning to record the work with the BBC National Orchestra & Chorus of Wales.
I've been warned not to post on this topic because it hasn't been touched for at least 120 days! Poor Holst. Anyway, I've had an EMI Classics CD (
The Hymn of Jesus and the
Choral Symphony) in my grubby mitts for a decade or so. The
Hymn I loved immediately and have played frequently. The
Symphony I haven't touched years. I honestly can't remember anything about it. I'm not sure, and I'm embarrassed to admit this, if I even played it all the way to the end. But I read somewhere recently somebody claiming that the
Symphony is Holst's masterpiece. So I'm going to give it another go right now. If I've suddenly seen the light, I'll come back and post in about 45 minutes.
