Spiritual Sounds of Central Asia: Nomads, Mystics and Troubadours: The world music calendar often features return visits by regulars who can be counted on to deliver a solid show and pack a concert hall; this tendency is understandable in business terms but renders exceptions like this one all the more refreshing. This Boston debut assembles 18 artists, with Azeri mughams (similar to Persian classical music) by Alim Qasimov, Sufi mystic music from Tajikistan by the Badakhshan Ensemble, and sounds from across the region interpreted by a female vocal ensemble. Echoes of the Silk Road and a welcome sample of artistry from a region usually associated with oil and problematic politics. At Sanders Theatre, Oct. 14. Tickets $28-$40. worldmusic.org, 617-876-4275.
