Yes, I'm impressed with the bits you can hear. A pity there's not more music however, and given that iTunes is the perfect place for people to pick and choose the bits they want, shame the Whitlock isn't available, or even Crown Imperial, Blest Pair, or the highlight, I was Glad. I wonder why they've been missed off? If it has been designed to fit on a single CD (for commercial release perhaps later), then there's enough music and the service to fit on to two CDs.
On the composer front, MacMillan's political views might have made for some awkward questions.
