I was at a concert in May, a very wonderful program of folk dances and songs, the real spirit of Georgia, high-level professional artists, especially pleased with the local youth who danced to the songs, this suggests that Georgia greatly appreciates and loves its national culture, very atmospheric, if you want to feel the local flavor, I recommend
The building is unique - completely wooden facade, looks epic) it's nice to be there, but there is no ventilation, in the evening you have to open huge, beautiful doors. Excellent acoustics, but there is not enough decoration of halls, sofas for waiting.
