CARSON, Calif. -- The LA Galaxy will hold #GalaxySocial Day on Sunday when they take on Seattle Sounders FC.

#GalaxySocial Day will be highlighted by seven-year-old Malea Emma Tjandrawidjaja singing the National Anthem. Emma won the #GalaxySocial Day Instagram Anthem contest, beating out many other applicants for the right to sing the anthem.
