I'm finally getting around to writing some things about Persian music, dastgah system, modulation etc. Here an article about Dastgah Mahur, it
includes a brief breakdown, soundclips of excerpts from the Persian Radif.
Good stuff!
It's pretty hard to find non-improvisational recordings of the radif with the oud online.
Very helpful, you should catalogue the rest as well, perhaps also invest in a higher quality microphone.
