I have gotten the Kilmartin Sessions and they are really great. There are a lot of songs there I am putting in my personal build for barbarian factions strat map music.

Persian Cataphract could answer some more on the Persian side, but he has pointed me towards some good stuff already. The best thing I've found so far are some songs from the Kudsi Erguner Ensemble, their CD Peshrev and Semai of Tanburi Djeil Bey. It has some vocals, but a lot of them are just instrumental and work very well. TPC and Angadil also have pointed out La Musique Savante Persiane by Sorouch Izadi and Djalal Akhbari, but it has too much in the way of vocals for me to really enjoy it on the strat map. Same problem with Shahram Nazeri's Mythical Chant (Kurdish Classical Music). Same problem also with Haj-Ghorban Soleimani's Tradition Des Bardes Du Khorassan.

Oh, by the way, the Roman music has a second CD out, *and* you can get both of them for 10 bucks each (USD) on audiolunchbox - mp3's. One is for wind instruments and the other for strings.
