We went to the concert by this group last night. This is a publicity photo off of their web site.
This is a photo I managed to take from the back of the church. We were so surprised to see Yadt Elyas playing the oud! We'd met him a number of years ago when he was living down the hall from us.
More information about this amazing organization can be found here and here.
We saw that there were some people in the group with visible disabilities, but didn't know that the group was dedicated to including them in the choeur.
We'll stop at the Cafetheque (a coffee roasting and drinking place down the street) one day soon, and ask Yadt (who works there) how he got involved with the group.
