Are there any other modern opera-stylized bands other than Therion (Secret of the Runes) and S.O.A.D.?

Hey there! I know it seems like a strange question, but I was wondering because I'm really into opera like Wagner [yes anything Wagner] and Mozart [especially Don Giovanni]. The only operatic bands I know are Therion [and I'm pretty sure it's only one album], and System of a Down [though really it's just the quality of the singer's voice that makes it so.]. I would love it if someone could give me some ideas as to what else would be good to listen to.
