Probably shouldn’t ask you about “Porgy and Bess”.
As a full-blooded Caucasian who therefore supposedly has no say in the subject...
I think Porgy and Bess is probably more true to the presentation of blacks than even the earlier Scott Joplin opera Treemonisha, in spite of the fact that the former was written by Brooklyn Jew and the latter by a black Texan. But both operas are worth experiencing, Porgy because of its basis in blues/jazz, and Treemonisha because of its basis in ragtime, both uniquely black American musical genres.
Especially the part where Porgy helps Porcelain make the bed.
Oh, wait that was Porgy and someone else.
