Besides the Ottoman music, Anatolia provides a rich heritage of music in various styles. The raspy tanbur is the principal plucked-string instrument of the region, and is also prominent in Ottoman music. A solo recital, with more of a "folk" inspiration:

Turquie: L'art du tanbûr
Talip Özkan
Ocora (Radio France) C 560042
This is Talip Özkan's second recording for Ocora, and both combine tanbur playing with singing. The songs & modes are taken from throughout Anatolia, and have a closer resemblance to some traditions of Central Asia than does the Ottoman-derived music of Kudsi Erguner. The forms remain makam-derived, and improvisation is an important aspect of this style. The result is something of a folk anthology, but delivered with great sophistication.

Some people apparently confuse tanbur with baglama and Maqam Music with Folk improvisation. Ethnomusicologists, where are you?
