Banjo

BB Bowness

Catherine “BB” Bowness

Born in the small town of Marton, New Zealand, Catherine “BB” Bowness spent her early years working and living in her family’s Fish-and-Chip shop. Although an unlikely origin for a bluegrass banjo player, New Zealand would offer BB her first introduction to the instrument, sparking a lifelong love and fascination. A world away from the heart of bluegrass, BB spent much of her childhood teaching herself the instrument, and through dedication and tenacity became New Zealand School of Music’s first banjo student. Inspired by her New Zealand predecessors, The Hamilton County Bluegrass Band, BB was always drawn to the five-piece full band, and after heading to America in 2012 she co-founded her current group, Mile Twelve.
