After winning the 2015 Sarah Vaughan International Vocal Competition and then performing at the Montreal International Jazz Festival the following year, 25-year-old singer and songwriter Arianna Neikrug makes her grander introduction to the music world with the release of Changes on Concord Jazz. Produced by the Grammy-winning pianist and arranger Laurence Hobgood, Changes displays Neikrug’s gift for interpreting tunes from the Great American Songbook and more recent pop and R&B classics from the ’70s. The disc also contains two originals that reveal some of Neikrug’s journey from her hometown of Los Angeles to New York City. Changes begins with a hypnotic reading of “No Moon at All” on which Neikrug initiates by pairing her comely soprano with Hobgood’s economical piano accompaniment. Soon after the rhythm section enters the fray and buoys her along as she demonstrates her assured sense of swing, bluesy phrasing and remarkable scatting acumen.
