I first heard about her from a Jello Biafra spoken word, in relation to her involvement in banning the album Frankenchrist and the H.R. Giger painting they included inside it https://en.wikipedia.org/wiki/Frankenchrist
She was key to that whole "Explicit Lyrics" sticker thing as well.
Some people write some awful lyrics but anyone who buys an album from an artist known to swear already knows this. Feinstein will rot in hell like the rest of them.
