On Sunday, May 13, 2018, at 6:00 PM, the Hamazkayin Gargach children's and youth choir gave a concert at the Zhirayr and Tsoline Khachaturian Concert Hall of the United Armenian College. Zakar Keshishian conducted the concert and pianist Liana Harutyunyan accompanied it.
Zakar Keshishian delivered a speech saying, ″Time has gone by so fast. Last year we celebrated the 20th anniversary of the establishment of Gargach, and this year in December, we performed the native musician Armenouhi Karapetian's oratory written for us. Today, we present our annual performance dedicated to five different beautiful occasions. This children’s choir gathered on the stage has a peculiarity. They sing in unison, and they take their first step towards the choir art to achieve greater professional heights in future as a professional teens’ choir, later as a youth choir, and then as the Kusan choir. We believe in our mission and will continue to do it″.
