Have you read Robert Creeley's work before? It's so wonderful. One of my favorites is titled "The Place", originally from his book Echoes and included in his Collected Poems.
Also loving and reading Charles Olson's prose- his essay Projective Verse. And his letter to poet Elaine Feinstein. There's a great piece about Cy Twombly....both were part of the Black Mountain poets.
What are you reading these days?
