I don't really care for King Diamond's falsetto vocals. His normal voice is high, but when he goes into falsetto range it doesn't do it for me. Sometimes I can enjoy them in a cheesy, silly way, but I feel they kind of clash with the often beautiful guitar riffs underneath. The vocals feel parodic in comparison; in a bad way, I think. If it weren't for the vocals, Don't Break The Oath might be one of my favorite albums of all time.
