The Stereotypes

During their 17-year history, The Stereotypes have enjoyed performing music from all genres and traveling across the country during their annual winter tour. Contrary to the group’s name, there is not a traditionally stereotypical member of the stypes because the group features an amalgamation of backgrounds, musical abilities and on-stage personalities. The group is ~tied~ together by their love of a cappella music, even while competing against one another in the annual “Mr. Stereotype” contest on Wash U’s campus, where each singer adopts and personifies a stereotype in hopes of winning the show. Also notable are the Stereotypes’ performances at Carnegie Hall in NYC, BOSS (an a Cappella festival in Boston), and the ICCA competitions, reaching the finals in 2011 and semifinals in 2014, 2015, and 2017. They’ve released 5 critically acclaimed studio albums which are available on Apple Music and Spotify.
