At yesterday’s on-stage rehearsal for Friday’s Shoghaken Ensemble concert, at the Aram Khachatryan concert hall, the group was interrupted by a small army of workers who came to set up the stage for a pop concert planned for the next day. We were amazed at the effort they put into their “show,” hoping only for their sake that their music matched up with their rich staging. In any event, with just a day remaining, activity is at a fever pitch for Shoghaken’s Friday evening performance, the very existence of an actual folk concert becoming a point of interest for much of the city’s population.
