Emily Krulewitz, creative director of the X-Factors, an a cappella group in Northwestern University (NU), said she has devoted much of her five years at NU to the group. Michael Kaish, the group’s music director, and Adam King, one of the baritones, talk about the way in which Emily has expanded their presence on campus. The X-Factors also won second place in their first national a cappella competition and released an album in May. Emily said she loves the group and hopes to continue her involvement in the world of a cappella. The X-Factors, she added, are special because they are fun and they are good at what they do.
