other worthy mentions :
Polydor Brian Eno-David Byrne : My life in the bush of Ghosts (UK,1981)****°
One of the first popular items sampling Middle Eastern Music. David Byrne was a real master in compiling rhythms here in dance / "song" structure. Unfortunately the master piece Qu'ran is not reissued on the cd because some idiots found it a blasphemy to God. Hahaha.
Enja Rec. Rabih Abou-Khalil & The Balanescu Quartet : Arabian Waltz (LEB/..,1996)***°
Popular Lebanese oud player. This is my favourite work of his. Composed Arabian Jazz Fusion music...
Deram 
East of Eden (compilation album)(UK)****°
On various tracks there's a combination of Middle East, jazz, and end sixties jazzy progressive rock, East of Eden were truly a unique group. Steve York studied oriental music in Turkey ?
First three albums are recommended.
a few interesting single tracks :
* Nihil Project's Paria starts with a great psych-techno track with Middle Eastern singing.
* Pochakaito Malko has a fantastic Middle Eastern track on Layla.
