Maxwell Byun and Brandon Tai are the powerhouse rhythm section from the semi-professional group, Seconds Apart (formerly known as COLLAB). Both instructors come from a background of competitive collegiate and post-collegiate a cappella groups. Specializing in EDM-style arranging and beatboxing, they have worked together to finesse the craft of incorporating specialized sound effects and beatboxing into A Cappella arrangements and hope to share their gained knowledge and experience to the rest of the rapidly-growing A Cappella community.
