Julian Lage's résumé includes membership in Gary Burton’s band and Eric Harland’s Voyager, and he’s collaborated with Fred Hersch, Nels Cline, and many others. Lage’s classical background and love of traditional American idioms are on full display on the unaccompanied acoustic guitar album World’s Fair. The opener, “40s,” immediately grabs listeners with its wonderfully resonant tones and sense of instrumental storytelling. “Peru” seamlessly combines classical and bluegrass elements, and on the gorgeous “Lullaby” the silences between the notes say as much as the sounds themselves.
