If you like Byzantine chant in Arabic, I recommend anything you can find by Met. Elias Korban, the recently departed bishop of Tripoli and al-Koura, Lebanon. He was very well known for his many recordings of Byzantine chant in Arabic, dating back to his days as archdeacon at the Cathedral of St. Nicolas in Brooklyn NY, back in the 1950s. He died c. 2009, if I remember correctly, so there are tons of recordings out there, many of which are available on CD from Alexia Publications
based in Quebec.
