This collection and its sequel are absolutely two of my favorite audible purchases of all time. I bought it for the Eugene O'Neill play, which I would now say is the weakest of the six, but still good. I can't recommend this collection highly enough. The other LA Theatreworks productions are good too, but the Pullitzer collections are as good as it gets.
I liked this piece, but I didn't love it. It's an imagining of what actually went on in 1947 when Hollywood executives met at the Waldorf Astoria to discuss their response to the refusal of ten Hollywood writers and directors to testify before HUAC. It's a fun piece mostly because of its portrayal of famous and colorful characters, like Metro, Golwyn and Mayer.
While the Waldorf Statement is mainly remembered today as Hollywood failing to stand up for the principle of free speech, this play makes a lot of two issues we rarely think of. The first was an ongoing anti-trust campaign against Hollywood, which eventually led to the end of "the studio system," which I wikipediaed as a result of this play and I invite you to do the same. Chasing imaginary communists, which ironically meant these powerful men colluding at the Waldorf, was seen as a way to get Congress to look the other way on their exclusionary business practices.
The second issue was antisemitism. This was only a couple of years after the end of World War II, and there was a perception of Jews and communists (and Jewish communists) having manipulated the country into fighting their enemy, the Nazis. Also, these powerful men had vivid and fresh images of a seemingly advanced country turning against Jews in horrific fashion. It's a good point that I hadn't fully appreciated in the broader story of the Red Scares, but I think it's a little overdone in this piece, hence my healine.
I'll mention that there are a lot of characters, all male, with deep, slightly accented voices tending towards hysterics. Usually LA Theatreworks does a very good job of picking voice actors you won't confuse, but they have their work cut out for them with this piece, and they only partly succeed.
I'm a huge fan of LA Theatreworks productions. I've you've just stumbled across them, consider yourself lucky: you've discovered one of the true gems of audible. I can't recommend them highly enough. Their acting and production values are stellar. They're incredibly powerful, emotional works. If you can, enjoy them as real quality listening, setting aside some time or perhaps on a long drive instead of on the way to work or on a treadmill or something.
That being said, the two Pulitzer collections are better than this one, which is still good, so start with those.
