Not yet BF, but looking forward to it. I have Cassandra's "Sing Standards" comp that Verve put out a few years ago, which cherry-picks from Blue Skies and some of her other early releases. I haven't listened to it much though, for whatever reason (probably because it's a comp).
I didn't really enjoy some of her pre-BN stuff that I've picked up (the live album & Dance to the Drums), but I should probably try some of the other ones at some point.
I think this one will be interesting though, and I like that Jason Moran's on it as well.
