just to add to the list of cast recordings with PA labels: Hedwig and the Angry Inch
I also think this chice to apply the label or not stretches into mainstream music. A few years ago My Chemical Romance released Three Cheers for Sweet Revenge which had the label and Modest Mouse released Good News for People Who Love Bad News which didn't. I wondered why MyChem's CD, which curses once or twice but it's muffled and cleverly alludes to homosexuality, suicide and sex, was slapped with a PA label and Modest Mouse's album which fequently cursed and made drug references was sticker free.
I guess it really can depend on what the label thinks and how they want to market it.
You're reminding me of people you hear at the movies asking questions every ten seconds, "Who is that? Why is that guy walking down the street? Who's that lady coming up to him? Uh-oh, why did that car go by? Why is it so dark in this theater?" - FindingNamo on strummergirl
"If artists were machines, then I'm just a different kind of machine...I'd probably be a toaster. Actually, I'd be a toaster oven because they're more versatile. And I like making grilled cheese" -Regina Spektor
"That's, like, twelve shows! ...Or seven." -Crazy SA Fangirl
"They say that just being relaxed is the most important thing [in acting]. I take that to another level, I think kinda like yawning and...like being partially asleep onstage is also good, but whatever." - Sherie Rene Scott
