He was born on March 18, 1963 in the city of Stepanakert.
He graduated from the school №8. He loved sports and playing musical instruments. His teachers Oleg Pirumyan and Vladimir Frumanyan were his friends. After graduating from the Polytechnic University, he started playing in “Artsakh” ensemble.
He was the artistic director of the Teacher’s House.
Avanesyan Garnik also liked to take photos. Everything that took place in Artsakh was demonstrations, rallies, broken buses by Azeris and so on. All these photos have been sent to the world by presenting the real events taking place in Artsakh. For the participants of the Artsakh movement it was necessary to bring from Yerevan many medicines (the Artsakh movement had already begun). However, Garnik died in the 1990’s as a result of a car accident.
