Artist: Old Worlds Song: "The Christmas Song"

Regular readers may remember how Old Worlds' looped, finger-tapping guitar acrobatics mesmerized me at ComFest. If you're curious to see for yourself, the band is playing a release show for its new four-song demo Saturday at Ruby Tuesday, 1978 Summit St., alongside This Is My Suitcase and Cat Swallower. "The Christmas Song," one of the selections from that demo, shows off Aaron Sturgill's knack for tastefully flaunting his mad guitar skills. The song breathes its way from delicate to delirious and back, and though it doesn't feature Sturgill's vocals, it's a fairly solid summation of what this band does well. Hear it at MySpace.
