When these artists keep to the exotic mix of electronics and Near Eastern spices it is, in my experience, unsurpassed in its originality and sheer groove power.
Where they veer away towards the more conventional rock idioms and a kind of hip hop meets "Tin Machine" it is much less successful.
The Oud is a wonderful instrument, leading here much of the time and magnificently; treated or not, but much of the grunge guitar is so familiar as to be cliché ridden. Where vocal is mainly used as texture and rhythm, it is fine but where they begin to become songs they are not resolved and sound like poor lyrics made up in the studio. Even if it is "Real World".
By and large the instrumental tracks are gorgeous, reminding me of the amazingly prescient 1975 Album "Shamal" by Gong (look it up!)
