Jack, for "western ears" Matar produces an unfamiliar sound on his instrument.
But: by closing the eyes and lying on a carpet (or something else) his music has a hypnotic effect.
This lp, which I possess was released by Philips, France (633703 APL). Comments were made by Christian Poche, director of the jeunesse musicales du Liban.
Must say, that I listened to it 2 or three times within 40 years without any deeper interest.
But as times are changing, obviously my spectrum of interest changed too. Now I'm going to like this very special kind of music.
