Read into a whispery microphone, read a poem, a line from your diary, a dream, read that letter, your song lyrics or, better yet, sing them, read from your work-in-progress novel.

“Call it a jamboree. Yet, let's make it verbal. The mic is open for those who reach for it. The suggestion is to read a text (any genre) or improvise on the spot. We encourage you to bring works of personal authorship.
However, if you would rather read a most cherished fragment from another writer, that works, too.
Or maybe you just want to tell jokes, even a string of punchlines. The time cap is seven minutes per person, but we won't count too strictly.” - Javier
