A member of the Northwestern community for over twenty years, Significant Others is proudly Northwestern's premiere all-female A Cappella Group




Sig O traditionally puts on 3 shows during the school year--fall, winter, and spring. All through the year, we sing at various gigs on campus and throughout the Chicagoland area including charity events, opening acts for other groups, new student week performances, etc. Every winter, Sig O also goes caroling around Michigan Avenue. 

Significant Others loves hosting other visiting groups, and have traveled and performed with groups from University of Michigan, University of Connecticut, Washington University in St Louis, University of Chicago, and DePaul University.

In 2010, Sig O auditioned for the popular hit TV series, The Sing-Off, caught the attention of the McNulty Casting Group and advanced to the contracting phase of the show.

Above all else, Sig O is a group of talented & involved ladies who love to have fun and sing together!
