Kassia Music grabs audiences with its energetic performances and programming  that frequently intertwines elements of classical and Eastern European folk. The ensemble regularly plays works by its founding composers, Sam Post and Bernard Vallandingham, who find influence from varied classical eras and musical styles. Formed in 2016, Kassia Music has appeared at the Kennedy Center, the National Music Festival, and the National Gallery of Art.  

Kassia Music has been the the ensemble-in-residence at the Episcopal Church of the Redeemer in Bethesda, MD since 2019. The residency involves concerts featuring a mixture of western music and original works by Bernard and Sam. Kassia also runs an annual Chamber Music Day event for young ensemble musicians and assists in programming the church's Friday Night at Redeemer (FNAR) series.

Kassia Music is a member ensemble of the District New Music Coalition.
