The Stereotypes

The Stereotypes are a TTBB (all tenor and bass) a cappella group from Washington University in St. Louis. Founded in 2001 as a fresh take on “stereotypical” a cappella, they sing music from genres ranging from pop and rock to soul and folk (and some originals)!

Their arrangements are all completely original and made by members or group alumni! They approach singing with a performance mindset, engaging their audience and communicating each song’s individual message.

They are best known for our annual concert, Mr. Stereotype, where they each embody their own “stereotype” and compete in their world-famous a cappella beauty pageant, all while coming together to put on an incredible vocal performance! Also notable are their 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, 2017, and recently in 2019. They’ve released 5 critically acclaimed studio albums which are available on Apple Music and Spotify.

Sur Taal Laya

Founded in 2018, Sur Taal Laya, or STL, is WashU’s premier Bollywood fusion a cappella group combining classic Bollywood hits with popular Western music. Sur corresponds to a musical note, Taal, the beat or rhythm which binds a composition in time, and Laya, the tempo of a composition. Together, Sur, Taal, and Laya create a complete musical experience and are therefore the namesakes of their group. They are a tight knit group that love to mess around but have also competed at competitions across the nation and qualified for the ICCA quarterfinals in 2019. They are also one of the groups that perform at Diwali each November.
