The mono on this title sounds amazing from this series. I had to check that it indeed was mono — almost sounds like stereo. Woods was 26 and Byrd was 24 when this recording was made, and, as young as that is, in my opinion it's some of their finest playing. Woods' compositions on this date are also noteworthy — not simply changes meant to blow over that had a title slapped on later.
One thing I've noticed with this series — little to no ear fatigue. You can turn the volume up, fix a beverage, sit back, and soak it up.
