I really enjoy listening to writers read their work out loud. There are a few really great reading series here in Chicago that consistently feature writers who not only have strong, engaging voices on the page, but also have a knack for giving that voice new life through the spoken word. I try to attend at least one reading each month, more if I can.
What I've taken from attending so many readings is this: there are great readers and poor readers, and the gulf between them is vast.
