Majcherczyk & Casal Duo has been performing together since 2021, debuting at Paul Hall at The Juilliard School. Subsequent performances include St. John’s in the Village in New York City, International Festival de Saint Malo in Panama, and a performance at the Polish Embassy in Panama by invitation. Their repertoire spans classical staples such as Mozart Duos, 20th-century works like Three Madrigals by Martinu, and lesser-known composers including Gordon Jacob and York Bowen. They also perform premieres, including duos written by Luis Casal for the ensemble and contemporary American composer Howard Lew. Recently, they were featured on the American Viola Society recording Hypnagogia.
