Grammy-nominated ensemble Sandbox Percussion recently showcased their utmost prowess in Beijing, delivering a mesmerizing rendition of Andy Akiho's composition, "Seven Pillars." Prior to their grand performance, CGTN reporter Xu Fei had the opportunity to capture the ensemble's meticulous rehearsals, where every nuance was honed to perfection. The journey of Sandbox Percussion began in 2011, when passionate musicians –Jonathan Allen, Victor Caccese, Ian Rosenbaum, and Terry Sweeney – converged, united by their shared devotion to chamber music and the pure joy of harmonious collaboration. Since then, they have been enthralling audiences around the world with performances that transcend the boundaries of both visual and auditory artistry.
