Everybody loves a parade, especially if it comes in the form of the shambling, rambling and fleet-fingered wiseacre known as David Mayfield. On one level, he's a simply astonishing bluegrass-guitar picker, raving his frets with a casually merry (but often dazzling) aplomb. On another level, he's a heart-rending songwriter with a plaintively mournful drawl on homespun reveries like “Human Cannonball.” He's perhaps best known for his collaborations with Mumford & Sons, The Avett Brothers and his sister, Jessica Lea Mayfield, but his own music is even more rewarding. His affecting songs and deft playing by themselves would set Mr. Mayfield apart from his peers in the crowded field of Americana, but onstage he's also a sublimely witty and marvelously entertaining prankster who could easily have a second career as a comedian.
