I've a feeling though she may be the sort of composer that gets damned with faint praise - 'well-crafted', 'attractive', that sort of thing - not that those are necessarily bad things at all in my book. The fact that her teachers include John Tavener and Robin Holloway probably doesn't help the street cred in some quarters
but she definitely seems to have been her own person from fairly early on. I suppose insofar as these labels mean anything she has to count as being in the 'conservative' rather than any 'radical' camp, but pretty good 'conservative' nonetheless?
Well, Robin Holloway was my teacher too, not that I'm sure I had much street cred even before admitting that, but anyway ...
I don't think Weir generally gets damned with quite the sort of faint praise you suggest, George - more often she seems to be placed in the 'witty/ironic outsider' camp, although sometimes on the basis of little more than that she's Scottish, female, and not given to overt displays of emotion.
I think
A Night at the Chinese Opera could fairly be reckoned her masterpiece (though I'm perhaps unfashionable in preferring to think of that term in its original sense of (something like) 'A*-grade graduation piece'). I don't know her second opera
The Vanishing Bridegroom, and
Blond Eckbert seems to me to suffer from not having a punchline.
I'm not surprised you don't remember which chamber pieces you heard, as I tend to find the supposed wit and quirkiness rather hard to perceive amidst the surprisingly dense (however spare or lucidly-scored) pitch manipulations, and without the wit and quirkiness all I do hear
is those manipulations, which makes me wonder if she's not quite the composer she's made out to be and if after all her music sometimes
is ... well, I wouldn't like to say 'well-crafted', 'attractive', that sort of thing ...
For me her undoubted theatrical gifts are better served by the broader brushstrokes of the orchestral music (with and without voice), of which you'll get to hear plenty next January. I don't think I'm letting slip any secrets in saying that NMC's new disc of five such pieces should be ready around the same time, and, having recently been getting to know the five pieces in question quite well, I'd certainly say it's one to look forward to.
I'm a little lost by the notion that Weir has anything very much in common with Benjamin and/or Adès, or that any of those have anything in common with the to my ears significantly inferior talents of Bingham, Burrell and Beamish. Radio 3 airplay preferences aside, it does seem to me that these sorts of discussions are generally better served by differentiation rather than generalisation, and that if people were actually willing to say what they thought about specific composers/pieces, rather than having to be in the 'I love all [mainstream orchestral C21st music / Havergal Brian/Robert Simpson-esque C20th symphonic music / fill in the blank]' or 'I hate it' camp, then we might actually have some common ground for debate. In the same way, Weir (just like any other composer) seems to me ill-served by the generalised advertising-slogan approach, which is why I've taken some trouble to explain why I 'get' her chamber music much less than everything else she does.
