I'm not sure where the choir is located (since I assume those were female voices I heard). I had assumed they were behind the iconostasis, but that seems not to be the case. Note the lavish use of the thurible with the incense representing the Holy Spirit.. There seem to be more participants in the liturgy than congregation. Note that it is a very iconographic oriented service. Enjoy !
Phew ! I can smell the incense sitting at my computer.
