No, only the Aimard. I'll investigate.
Besides those Piston concerti I'm also inclined to recommend Sessions' entry in the genre. But I notice that Naxos doesn't have any of his works. I wonder why.
I was wondering if any of you had saved some of the discographies Mosaic provided on their website. I'm looking specifically for the Lee Morgan and Andrew Hill sets. Would someone be able to e-mail me these?
