Well, OK but given just how many live recordings Jarrett has released, odds are no-one has heard them all. ;o)
There aren't as many live Miles releases (definitely not hundreds) but the "Bootleg Series" has certainly increased their number.
I don't know why Harrell isn't better known. Or Charles Tolliver, for that matter. I haven't heard any live Harrell recordings. Have you? We're focusing on live releases, here. Accordingly, can you suggest a live Steve Turre recording you like?
