Won't be in the area at festival time.
I like the lovely city of Marciac when it is not crowded with jazz aficionados!
But I will listen to the live brodcasts on France Inter radio from several evenings (Shorter, Rollins, Zorn, Hank Jones...) and watch the concerts when they show up later on the Mezzo TV chanel.
Hope you have a good time Steven! and don't drink too much Colombard
