The Bon Iver hype-machine is alive and well. Fresh off of his trip to visit the Colbert Report, Jimmy Fallon invited Justin Vernon and his “Bontourage” back on the program. This is their second trip in less than a month. This time, we got a track off of the new S/T album. Drive-By Truckers stopped by Letterman to perform the standout track, “Everybody Needs Love,” off of their latest album, “Go Go Boots.” I always tend to feel better about myself after listening to a DBT album, because the characters in their songs are pretty flawed.
