Greek pianist and vocal coach Christos Marinos has appeared in collaborative piano recitals, and in concerts as a member of the piano duo Duo Vivo, in New York, London, Vienna, Innsbruck, Athens, Thessaloniki and other European cities. He has premiered works by Greek and foreign composers, some written for him, in Europe and the United States. Christos’s passion for music is not limited to performing. He plays for the studios of Metropolitan Opera singers, and has played for coachings at the Lindemann Young Artist Development Program. He explores and performs lesser-known art songs, writes music articles, translates music books, participates in summer festivals in Greece as a vocal coach and music director, gives lecture-recitals, and works as a music researcher. He is passionate about Greek Art Music, and his goal and current research project is to present the vast and undiscovered world of Greek Art Song to singers and pianists, as well as to audiences, in the United States.

In 2017, together with dramaturg and stage director Antigoni Gaitana, they founded the Colla Voce Workshop, the first of its kind in Greece, for classical singers and collaborative pianists. It takes place at the Horto Festival in the summer, and in Athens in the winter. The workshop's first project was the Greek premiere of a fully staged production of "Riders to the Sea" by Ralph Vaughan Williams. Also in 2017, he became a basic contributor to the Archive of Greek Classical Composers. In 2002, he was appointed curator of the Jani Christou Archive in Athens, position he held for ten years. Since 2003, he collaborates with the Horto Festival, where he curates and plays for vocal masterclasses by distinguished artists, and appears in piano duo recitals with Nikos Adraskelas. He has worked as adjunct instructor in piano studies at New York University, and is currently staff accompanist at the same school.

Christos has recently been accepted as a doctoral student at the University of Minnesota, focusing on vocal accompaniment and coaching. He received the Master of Music (M.Mus.) Degree in collaborative piano from New York University (studio of Grant Wenaus), and holds diplomas in Piano Performance, Tonal Harmony, and Baroque and Renaissance Counterpoint from Conservatories in Greece, as well as the Recital Certificate in Piano Performance with honors from the Guildhall School of Music and Drama. Very significant to his development was his association with pianist, conductor, pedagogue and author George Hadjinikos (1923-2015), with whom he studied privately for ten years. In addition, he has taken cello, voice and conducting lessons, and has participated in masterclasses by Eteri Andjaparidje, Evgeny Kolmanovich, Diane Birr, Zouzou Nikoloudi a.o.​
