As I was browsing thhe NY Times website there was an article about Ornette Coleman and low and behold his bass player can be seen in the background playing what appears to be a Persuader? Not as familiar with the basses as I with the guitars.

i saw ornette last year at town hall in nyc, and he did have a guy playing a persuader with piccolo strings on it. i don't remember the guys name, though. i wrote a review of the show on here, but that was a while back.
and, just ftr, ornette is god. or something very, very close.

I think he is showing up in my locality  soon. I will have to go hear him !

Apparently, the bass player is .

That's high energy fusion for sure, I remember seeing Michal  Urbaniak  a long time ago in  San Francisco at the old  Keystone Corner in the North Beach District.That must have been back around  the mid 1970's  . Of course he had a different line up of musicians .  Thanks for the link to the video Dave .I hope  that if Andy Macdowell plays with Ornette when I go see him he will bring an ALEMBIC BASS !

When I him in Portland last year he had 3 bass players and a vibes player. Very cool show. At that time the fretless bass player was playing an Essence 5 string fretless. I love the way Ornette plays trumpet like Miles. Although I heard it drove Miles nuts. I think it's cool that the old cat still picks up new things and incorporates them into his show!

I thought he was awesome in Groundhog Day.
