The Ahn Trio is a classical piano trio composed of three sisters: Angella (violin), Lucia (piano), and Maria (cello) Ahn; Lucia and Maria are twins. Born in Seoul, Korea, they moved to New York City in 1981, and began their training at the Juilliard School. The sisters formed a trio while they were earning their master's degrees at Juilliard. The Ahn Trio is known for its performance of new classical music, genre-crossing programming, and collaborations with other artists.
