There are jazz singers. Then there is Judi Jackson. Hers are the qualities possessed by the greats. Astounding range. Immaculate pitch. That indefinable ‘thing’. A twenty-something from small-town Roanoke, Virginia, Jackson arrived in London in 2017. Her first national tour, and subsequent dates in Europe, sold out. Little wonder: alongside covers of tunes made famous by her idols - Bettie, Billie, Ella, Nina – are originals that sound like classics, many of them showcased on her 2017 EP, Blame It On My Youth: ‘Still’, a meditative ballad with mystical clout.
