* He had been in Ashgabat
* Ashgabat is the capital
* While in Ashgabat he attended a concert of "cultural figures" [I'm still not sure what that is] of the Republic of Armenia and Turkmenistan. (Could you say "He attended a concert of Armenian and Turkmenistani performers"?)]
* He attended that concert with Turkmenistan President Gurbanguly Berdimuhamedowat
* The concert was at the Ruhiyat Cultural Palace
* He is now heading to Turkmenbashi City
