Thomas Oliverio can most typically be found effortlessly strumming a mandolin or some other stringed instrument with his Kentucky-based experimental folk/bluegrass outfit, Bawn in the Mash. But with The Faraway Frequency, Oliverio and his cohorts employ some decidedly more … well, far-out instrumentation and techniques. The Faraway Frequency — who feature The Faraway Stringband live — use sound collages and looped noises to, in Oliverio’s words, “[merge] the ancient tones of Appalachia with today's digital media.” It’s a dichotomy that’s just as intriguing and even more pleasant than it sounds, as with the bobbing future-folk tune “Boom Town” — it’s a track that sounds like an Appalachian time capsule beamed across the furthest reaches of our galaxy. Had they existed just 30 years ago, when Carl Sagan was putting together his now-legendary Voyager Golden Record to launch into space, The Faraway Frequency would have made good intergalactic ambassadors. Oliverio will also be appearing with Bawn in the Mash tomorrow, Friday, Aug. 27, at fooBar 2 in East Nashville.
