Looking for Symphonic Metal Bands with male Operatic vocals...?

The 69 eyes
Powerwolf (although it is a bit power metal like)
Therion
To Die For

I hope this is some useful information.

Rhapsody of огонь is the first that comes to my mind.

Iced Earth and Iron Maiden both have operatic male singers and use keyboards, although I wouldn't really go as far as to call them symphonic.

Trans-Siberian Orchestra has a lot of different singers (some male and some female), some of which are operatic and a lot of keyboards.

THERION (obviously), although they also use several female singers as well. In studio they have lots of truly operatic male and female voices, soloists and choirs.

DANTESCO from Puerto Rico. They have a highly operatic baritone lead singer, very different from power metal falsetto singers. He sings in Spanish (don't know if that's a problem).

Matt Barlow, te ex-singer of ICED EARTH, sings at times with a clean, deep, semi-operatic voice, but also does еще aggressive, raspy singing, as well as high pitched falsettos
