Spalding Gray. I've written about him before--
here, 
here, and 
here. I can't say how sad I am to know he's dead. What a brilliant man. There are many monologuists, including one I love as much as Spalding Gray, but there is no one else at all like him. I have driven all over the country listening to my tapes of 
Monster in a Box over and over. Also 
The Terrors of Pleasure. Everyone should see 
Swimming to Cambodia. We saw him perform 
Gray's Anatomy here at the University Theater years ago, with his plain table and chair and notebook and glass of water. From the 
NYT:
It was a muted end for Mr. Gray, whose singular talent was closely observed autobiography, performed in a style that alternated between conspiratorial whispers and antic screams as he roamed through topics large and small.
Very, very sad. Hearing his monologues, I always found it hard to believe he could have been as sad and he was saying he was, because he was so funny and so deep. I'd like to think he wouldn't have left us if he hadn't also been in physical pain. Love to his wife and children.
