Thousand Oaks, CA native Katherine Ho went head-to-head with teammate Lily Green, singing a duet of “Lovefool” by The Cardigans. Katherine beat Lily, and Adam named her the winner of the battle.

Both of Katherine’s parents have graduate degrees and work in science, but that didn’t stop the 16-year-old from pursuing her music dreams. A child of Chinese Immigrants, Katherine started playing piano at five and moved on to vocal lessons at nine. Her career was kick-started when her vocal teacher got her a professional gig as a session singer for the film “Valentine’s Day.” Last summer, Katherine was accepted to the ‘A Cappella Academy’ summer camp, which was founded by Pentatonix’s Avi Kaplan.
