Mikaela Davis is the kind of songwriter who routinely defies expectations. The 25 year-old artist is a composer of striking maturity. Her arrangements deftly combine elements of rock, folk and pop, and her vocals display a wisdom and a ruefulness that belie her years. Davis’ instrument of choice is the harp, which she has played since she was eight years old, right about the time she could actually get her hands around the instrument. A native of Rochester, New York, she spent her formative years in youth orchestras rather than in garage bands and later earned a degree from the Crane School of Music.
