From all three available recordigns of Khachaturian's Symphony No.2, I would rank this one between No#1 (Khachaturian/VPO) and No#3 (Tjerknavorjan/Armenian PO). But due to terrible, unacceptably poor sound quality of Decca VPO recording, many people will choose slightly worse interpretation with Jarvi, instead of ultimate, but badly recorded Khachaturian's own one. Anyway, this recording of the symphony is good.
Few excerpts from Gayaneh are not good, honestly - they are performed really messily (sorry to say this) - so I am not rating it with any stars. For this composition, I'd strongly recommend you Temirkanov with Royal Philharmonic, they are unbeatable.
