I was quite pleased to come across this rather small but wonderful channel of rare Armenian music:
http://www.youtube.com/user/Armen1491/videos?flow=grid&view=0On this channel you'll find music in all genres (operas, symphonies, concertos, chamber music and songs) by Armen Tigranian (1879-1950), Arsen Harutyunyan (1980-), Avet Terterian (1929-1994), Aleksander Spendiarov (Spendiarian) (1871-1928), Jivan Ter-Tatevosian (1926-), Edgar Hovhannisian (1930-1998), Grigor Egiazaryan (1908-1988), Haro Stepanian (1897-1966) and, of course, Khachaturian. Except for Terterian (whose music is powerful but difficult) and Harutyunyan, all the composers featured on this channel write in a tonal, melodic style. Spendiarov, a late-romantic, is an especially fine composer whose orchestral music can also be found on the channel of robt0007.
