Austin's Sleepwalker Releases "Blackbird"

There’s something dark and mysterious surrounding the Austin-based Sleepwalker’s “Blackbird,” the latest single off the group’s Holy Hell album. Filled with dissonance, shouted vocals from a distance, and a pummeling rhythm section, the song drives at 75 MPH before they smash into a brick wall and singer Brian Blevins’ voice smashes right through it.
