Barbara Dennerlein's CDs are available in the U.S. from cdbaby.com.
I've picked up a couple recently.
In a Silent Mood. Very nice solo album.
And Spiritual Movement No. 2. This one is amazing, jazz on a giant pipe organ.
This was the other "new" New Bird release (the version obtainable from amazon is a CDR).

The stray track with Milt Buckner is a nice one.
Recently, I've stumbled across a couple of Bird CDs containing broadcast material of good quality that I haven't heard. Here's one of them.

The Massey Hall concert was on May 15, and there are a couple of excellent quartet studio dates in the temporal vicinity for Norman Granz: the date which produced Chi Chi, Now's the Time and Confirmation was on July 28, and there was a December 30, 1952 date which produced Kim and Cosmic Rays.
