Chet, I'm not an expert but I agree there MUST be other techniques to record choral music, but this producer seemed to not care much about the group, but just obtain what I call "samples" of our voices. There was a moment when he said "let's try with few voices", then the director selected the first line of tenors, basses, etc. and formed a small group. 40 people had to wait almost an hour with nothing to do, while the small choir was recorded. In other passage we almost kill him, because he said "hmmm.. it is a little too .. eer.. too ACADEMIC " :)
