I'm listening to Middle Eastern music almost exclusively this weekend, trying to pick something to do a short choreo for.
As a starter, I'd recommend a Putumayo sampler disc
to get a sense of which types of Middle Eastern music you like best.
Definitely take advantage of Youtube to check out some of the artists.
I'm addicted to Hamid Zaki these days. He's sort of modern Egyptian folkloric (not folk music as we talk about it in North America).
It's pretty good party music.
The Putumayo Gypsy Groove c.d.'s also quite good - gives examples of North African/Moroccan/Spanish/Eastern European gypsy offerings. Very different from the jazz/pop sound of groups like the Gypsy Kings.
