One of my favorite sonneteers! Ms. St. Vincent Millay's poems give me iambic pentamerous chills. I wanted to post her classic "What lips my lips have kissed" or "Only until this cigarette has ended," but alas, I couldn't find accessible versions of her reading either of these. I'm sure they exist somewhere.
Here is her reading "Love is not all."
Ms. St. Vincent Millay's voice is quite Marlene Dietrichy. It's so strange to hear these well-known poems read aloud by their authors -- their voices never cease to surprise me.
