Liam St. John, the blues/rock heavy hitter out of Nashville, today released his newest single, “Greyhound Bus Blues,” featuring GRAMMY Award winning bluegrass artist Molly Tuttle. An acoustic video of the song with both Liam and Molly also premiered today on Bluegrass Situation. While the song initially strikes as a high energy, toe-tapping hit, the frank lyrics explore St. John’s journey from Oregon to Nashville, and the demons he may or may not have been running from.
