I thought I'd do some research on Russian a cappella repertoire but can't get very far when there is no followup to threads like: http://www.choralnet.org/174472 , even when some discussion has occurred in the past: http://www.choralnet.org/196092 . Could the " This thread is closed to comments" boilerplate have a link pointing to some kind of rationale, or am I supposed to have read that already elsewhere?
