Repper’s album with the New York Youth Symphony and Michelle Cann, featuring debut recordings of works by Florence Price, Jessie Montgomery, and Valerie Coleman, reached #1 on the Billboard Chart, and won a GRAMMY® Award, marking the first time a youth orchestra won Best Orchestral Performance.

On August 1, 2025, Repper releases an album of world-premiere recordings of newly uncovered works by the pioneering British composer Samuel Coleridge-Taylor to coincide with his 150th birthday in collaboration with the National Philharmonic and Curtis Stewart. Released on AVIE Records, the album includes Ballade, Op. 4 for Violin and Orchestra, featuring Curtis Stewart, and the tone poem Toussaint L'Ouverture. Accompanying the album will be newly available, free open-source performance materials for Toussaint L'Ouverture; Ballade Op. 4 for Violin and Orchestra, and 5 Negro Melodies (arr. Samuel Coleridge-Taylor). 

Repper has collaborated on large-scale productions of symphonic and theatrical works with the Weill Music Institute at Carnegie Hall, the Chicago Symphony Orchestra, Ravinia Festival, Peabody Institute of Music, and the New School of Music, among others. An avid pianist, he regularly performs as a soloist alongside his orchestras and choruses, and as an orchestral player. Recently, he played with the Chicago Symphony for its performances of Bernstein’s Mass, which was broadcast on PBS Great Performances. ​

​Alongside the standard repertoire, Repper is invested in programming new music and showcasing fresh talent. His ensembles have performed dozens of world premieres and pursued innovative commissions, as well as a variety of Carnegie Hall premieres from established and emerging composers. A trusted ear, Repper is asked to assist and cover at orchestras nationwide, including the St. Louis Symphony, the Van Cliburn Competition, and for Naxos recordings with the Peabody Symphony Orchestra.

Repper recently concluded his tenure as Music Director of the New York Youth Symphony, and as Principal Conductor of Sinfonía por el Perú — the elite youth orchestras and choruses of one of South America’s most versatile social-impact music programs. Repper was the Baltimore Symphony Orchestra Conducting Fellow for two seasons, and he served as the BSO’s New Music Consultant. For his success at these ensembles, and his growing profile as a guest conductor all over the world, Repper was awarded a Solti Foundation U.S. Career Assistance Award in 2020, 2021, 2022, and 2023.

His experience with choruses has been recognized with significant positions, including his tenure as the Music Director at the Baltimore Basilica, the first Catholic Cathedral in the United States. Internationally, Repper has performed with highly regarded ensembles and in the world’s greatest venues, including the São Paulo Symphony, at the Palau de la Musica in Barcelona, and at Carnegie Hall.

Repper has made two performance appearances on CNN, most recently with the multi-platinum selling artist Billy Ray Cyrus. His discography includes the aforementioned album of music with the New York Youth Symphony, an album with the GRAMMY®-Nominated Metropolis Ensemble and GRAMMY®-Winning Brooklyn Youth Chorus ("Musical America"), and several with the Peabody Institute as an Assistant Conductor. With the New York Youth Symphony during the coronavirus pandemic, Repper was one of the first to pioneer the practice of using video for orchestral performance across long distances.

Repper complements his work with professional orchestras with a firm commitment to education, and travels worldwide to work with ensembles of young musicians. As Artistic Director of the Chamber Music Society of Maryland, he ushered in a slate of innovative educational programming, such as the Reinecke Youth Chamber Music Scholarship and Fellowship Program. He has conducted several masterclasses for orchestras from all over the United States on behalf of the New York Philharmonic, and conducts side-by-side and educational concerts with major orchestras, including the Baltimore Symphony and the Colorado Symphony.

Repper believes that a conductor should connect people and allow music to be a vehicle for positive change. He continues to draw inspiration from his mentors Marin Alsop and the late Gustav Meier.
