I count six orchestral works by living composers and six chamber works by living composers. Looks like two of the 50th anniversary commissions for the BSO Chamber Players are by women, plus...argh, Amy Beach's dreadful piano quintet makes its appearance. So, two of 12 new pieces are by women and 1 of the rest is by a woman.
UPDATE: Oh, wait, links:
The web site itself is useless: they still have a format where you see a photo and a tagline for a concert, but can't see who all of the performers and works are without clicking through and mousing over. Folks, this is the worst possible design. Alex Ross and I have been complaining about this kind of thing for years. Just stop doing it.
