The Dolls Of New Albion, A Steampunk Opera by Paul Shapera.
It's an opera that he wrote in New York. I've never been able to find a performed trace on it on youtube though before. But I still listen to it constantly on Mochalab.
It's an opera someone wrote from what I can tell.....it's not an official Musical Genre but is a sub category of the Opera genre as it has elements of classical Opera.
