You may not know Carla Bley but she is well known to jazz aficionados and at the age of 82 she is still playing and touring and will be appearing at London's Jazz Cafe at the end of this month.
As you can see from the Wiki entry she has had a rather interesting life and has always been a keen 'musical explorer' having collaborated and recorded with musicians from other musical genres. She has recorded with Jack Bruce (on her jazz opera called "Escalator over the hill" - too long to include here) as well as Pink Floyd's drummer Nick Mason on "Nick Mason's Fictitious Sports" which is a Carla Bley album in all but name.
The first video here would have been better if Steve Swallow had used his acoustic bass instead of the bass guitar but that is just my own personal preference.
I have also included a live version of "Boo to you too", an oddity from the aforementioned Nick Mason album.
