KJ (Kenneth Joshua) McDonald, age 17, is a senior at Advantage Preparatory Schools in Santa Clarita, California. He began violin study at age six and currently studies with Lorenz Gamma. Since 2012, KJ continues study with the Perlman Music Program (PMP). A PMP scholarship recipient, he is one of 17 young violinists chosen worldwide by renowned violinist Itzhak Perlman. PMP includes a seven week Summer Music School in Shelter Island, NY and a two week Winter Residency in Sarasota, FL each year. At these various sessions he receives daily group and weekly private instruction from Mr. Perlman along with additional coaching from the Juilliard school faculty Catherine Cho and Li Lin. KJ appears as a soloist and a chamber musician for various PMP concerts. He was one of ten violinists to study and perform at the April 2014 PMP Israel Residency in Tel Aviv, Israel Conservatory of Music. KJ has also received personal instruction from Masao Kawasaki at the Aspen Music Festival 2010. The City of Huntington Beach formally presented its “2012 Good Samaritan Award” to KJ for his brave actions saving his father’s life during a surfing accident in which his femoral artery was punctured. At age 14, keeping a cool head, KJ carried his unconscious and much heavier father through the blood-drenched, rough surf, while yelling for lifeguard assistance. Undaunted by this trauma, surfing is still a big part of KJ’s pastime.
