Heads or Tails, the debut album by trio huH Robots, hearkens back to a time when music was made on front porches, not on GarageBand. This blues-tinged folk outfit, featuring Rosella Pearl and Kelly Newton on vocals and Adam Copelin on bass, tackles hot-button issues like mountaintop removal on “Appalachian Gold” and then blows off some steam with the somewhat defeatist anthem “Drink It All Away.” The raw sound quality makes it seem like you’re sitting on the porch with them as they pick and strum through melodies. This is classic storytelling put to music — set in Kentucky. I hear huH Robots’ live performances are infectious. See for yourself when the play at Wick’s on Baxter Avenue Friday night.
