I saw a new production of Show Boat by Jerome Kearn - Oscar Hammerstein II at the WNO. It's co-produced with San Francisco, Chicago and Houston. The production creator, Francesca Zambello, is now the artistic director for the WNO. She posed a question whether this shouldn't be considered the America's first opera (as it predates Gershwin's Porgy and Bess). I was skeptical but I am all for it after seeing it.
I loved the way Morris Robinson sings the"aria," Old Man River

I don't care if it's opera or Broadway -- it's good. Man, I had chills going down my spine when he went down deep to sing the Old Man River.
You gotta see it when it comes around in your city. Chicago already had it. So I imagine it will come to San Francisco and Houston soon.
