As Kyp Malone (TV On The Radio, Rain Machine) tells Fader, there is a big difference between Dylan on a t-shirt and TVOTR on a t-shirt. He's half-wrong, but only half because he's talking about legends.
At least the irony of him wondering what it would be like without Facebook and cell phones and the Internet right after he checks his Blackberry is thankfully not lost on him.
At the end of the day, it's just about creative outlet for him. I dig that, partially because it explains why his art is so different and so good.
