Sorry CT. I did a lot of research when writing for Valley of the Kings. I found lots of bands working out of the Middle East. There are some wonderful Christian bands (beautiful harmonies), but I didn't find any that sing in English as a rule. The ones I found that sang in English were either mixed faith (Christian, Islamic, Jewish), Islamic, or atheist. That said, with the exception of death metal bands, the subject matter tended toward the prim side of the fence, i.e., clean subject matter, no swearing, etc.
I did find a few Christian instrumental bands playing with middle eastern instruments though.
