PianoArts Artistic Team


Andrews Sill
Music Director

PianoArts Music Director since 1999, Andrews Sill is also Associate Music Director of New York City Ballet and Music Director of Milwaukee Ballet. Praised for his “strong artistic abilities, musical versatility, and winning personality,” Maestro Sill is known for conducting a broad spectrum of repertory from established masterworks to premiers of symphonic, operatic, and ballet works. Active as a concert pianist, Andrews Sill is one of few artists who perform concertos leading the orchestra from the keyboard.

Before joining New York City Ballet, Mr. Sill enjoyed highly successful tenures as Music Director of the Lubbock Symphony and the Sheboygan Symphony. Associate Conductor of the Milwaukee Symphony Orchestra from 1997 to 2001, Mr. Sill joined the MSO as Assistant Conductor in 1995. He previously held the post of Associate Conductor with the Virginia Symphony and the Florida Symphony Orchestra. He began his career as Assistant Conductor of Boston Ballet from 1988-1990.

As a guest conductor, Mr. Sill has appeared throughout the United States, Europe, South America, and Australia. He has also served as cover conductor for the Chicago Symphony Orchestra.

Mr. Sill studied both piano and conducting from the age of fifteen at Yale University, receiving his bachelor’s degree with honors. He continued his education at the Manhattan School of Music, earning his doctorate in 1987. He is an alumnus of the Aspen Music School, the Ravel Academy, and the National Conductors Preview of the League of American Orchestras.


Under the guidance of Maestro Sill, pianists learn how to navigate the professional orchestra rehearsal – communicating with the conductor, coordinating editions and rehearsal markings, and reviewing proper rehearsal and performance etiquette. Each semifinalist meets privately with Mr. Sill and performs with him and a chamber ensemble of orchestral musicians. Finalists rehearse full concertos with Mr. Sill and a chamber ensemble prior to rehearsing and performing with the full Milwaukee Symphony Orchestra under the baton of Mr. Sill.
