When the extraordinary Ponticelli cello quartet performed at Big Picture Foundation’s September 22, 2019 benefit, many local families had the chance to hear Rye High School 10th grader and longtime Big Picture Foundation member, Sean, Yu, play with three fellow prodigies, Chelsea Lim, Dylan Shih Wu, and Jenny Jiang.  The musicians mesmerized audience members of all ages and inspired many of the kids to go home to practice their own instruments.  Everyone present felt fortunate to hear work from four of the most talented musicians in the world.
