Dalton — Grace Kelly was 14 when she made her debut as a soloist with the Boston Pops and 16 when she performed at President Barack Obama’s 2009 inauguration. Now an internationally touring saxophonist, singer, and composer, she brings her quartet to the Stationery Factory at 8 p.m. on Friday, Aug. 14. Kelly’s concerts combine jazz standards, original compositions, pop influences, and spontaneous improvisation. Kelly began performing professionally as a teenager and has built an international career in jazz. In addition to performing, Kelly is an educator and co-founder of Saxy School, an online saxophone program.
