I wish I could say that it’s been years since I’ve thought of Juiceboxxx when he tells me, out of the blue, in a text message one night in September, that he’s coming to New York. The truth is I have been thinking about him a lot — periodically checking his blog, wondering what city he’s living in, hoping he’s doing all right. A series of videos he has started uploading to YouTube every week, in which he stares in a sickly manner into a camera and talks in awful circles about his upcoming projects, has left me with the distinct impression that he is on the verge of cracking up.
