Kantorei performs mainly contemporary, baroque, and renaissance choral pieces which are rarely performed in the Kansas City area. The seventeen voice choir performed for the 2013 Missouri Music Educators Association state convention and earned critical acclaim by area critics for its more recent performances, including a 2014-15 Season "Editor's Picks" top ten of the year nod by Metropolis.org editor Lee Hartman. Kantorei is currently working on its second album for the Resonus Classics label in England and is booking tours.
Most performances are a capella without amplification. KantoreiKC asks that there be table and chairs set up for volunteers to sell recordings and memorabilia.
