I don't know what Jack would think about Railroad Earth's music, but I bet he would be honored that a band took their name from his short story, "October in the Railroad Earth" (which I highly recommend, by the way). Their music is eclectic for sure. This article describes them as a "bluegrass, rock & roll, country and eastern jam band."
My band, The NitPickers, does a Railroad Earth song called "Dandelion Wine."
For today's Kerouaction you have choices. Read some of Jack's short story, listen to him reading from it, or listen to the music of Railroad Earth.
All in honor of Jack Kerouac Month!
