Thanks all for your input.
It was a great concert. Ornette´s blowing was powerful, with his particular phrasing and his incisive tone. Ballads, blues, latin rhythms, some classics ("Lonely Woman", "Turnaround"...) and some "outter" stuff.
Denardo Coleman´s unsubtle drumming was the worst part of the concert (happily, the volume was quite reduced for the drums!).
Not just a piece of nostalgia. A REALLY GOOD performance (imho)
