Archie Shepp and Abdallah El Gourd played a series of three concerts in and around Paris last summer (I believe), which were then recorded and put out on this disc, available so far only through Amazon.fr.
I listened to most of it with Abdallah last night. The concerts were largely unrehearsed, so it's impressive that the groups (Archie's quartet and Abdallah's quintet) so together. What's also important is that Abdallah begins each song but the last one, and he also sings on them.
Archie and Abdallah are going to tour again in April, I believe, around France and then coming to the West Coast in June/July, for sure a concert in San Francisco.
