The Grant Park Orchestra was formed in 1944 when the Chicago Park District assembled a single resident orchestra under the direction of Principal Conductor Nikolai Malko to perform at the Grant Park Music Festival (which began in 1935 and featured a series of visiting orchestras). Since then, other prestigious conductors have held the position, including Irwin Hoffman, Leonard Slatkin, David Zinman, Zdnek Macal and Hugh Wolff. In 2000, Carlos Kalmar was named the Festival’s Principal Conductor.

Today, the Grant Park Orchestra draws its musicians from different orchestras and musical institutions throughout the United States. Each summer, all of the orchestra members gather in Millennium Park for a ten-week long season consisting of intensive rehearsals and performances. During the year, the musicians can be found across the country performing with major orchestras, teaching at numerous universities and appearing frequently in concert stages across the country. Some organizations represented by Grant Park Orchestra musicians include the Lyric Opera of Chicago, the Metropolitan Opera, the Buffalo, Colorado, Jacksonville, Kansas City, Milwaukee, New Mexico, Phoenix, Pittsburgh, Richmond, San Antonio, Seattle, and Utah Symphonies. The Grant Park Orchestra was nominated for a Grammy award for its recording entitled Robert Kurka: Symphonic Works.

Described as bringing an “artisan storyteller’s sensitivity… shaping passages with clarity and power via beautifully sculpted dynamics… revealing orchestral character not seen or heard before” (Arts Knoxville) Lawrence Loh enjoys a dynamic career as a conductor of orchestras all over the world.

After an extensive two year search, Lawrence Loh was recently named Music Director of the Waco Symphony Orchestra beginning in the Spring of 2024. Since 2015, he has served as Music Director of The Syracuse Orchestra (formerly called Symphoria), the successor to the Syracuse Symphony Orchestra. Loh will hold this position until the end of the 2024-2025 season. “The connection between the organization and its audience is one of the qualities that’s come to define Syracuse’s symphony as it wraps up its 10th season, a milestone that might have seemed impossible at the beginning,” (Syracuse.com) The Syracuse Orchestra and Lawrence Loh show that it is possible to create a “new, more sustainable artistic institution from the ground up.”

Appointed Assistant Conductor of the Pittsburgh Symphony in 2005, Mr Loh was quickly promoted to Associate and Resident Conductor within the first three years of working with the PSO. Always a favorite among Pittsburgh audiences, Loh returns frequently to his adopted city to conduct the PSO in a variety of concerts. Mr. Loh previously served as Music Director of the West Virginia Symphony Orchestra, Music Director of the Northeastern Pennsylvania Philharmonic, Artistic Director and Principal Conductor of the Syracuse Opera, Music Director of the Pittsburgh Youth Symphony Orchestra, Associate Conductor of the Dallas Symphony Orchestra, Associate Conductor of the Colorado Symphony Orchestra and Music Director of the Denver Young Artists Orchestra.

Mr. Loh’s recent guest conducting engagements include the San Francisco Symphony, Dallas Symphony, North Carolina Symphony, Baltimore Symphony, Sarasota Orchestra, Florida Orchestra, Pensacola Symphony, Atlanta Symphony, National Symphony, Detroit Symphony, San Diego Symphony, Seattle Symphony, National Symphony (D.C.), Utah Symphony, Rochester Philharmonic, Indianapolis Symphony, Calgary Philharmonic, Buffalo Philharmonic, Albany Symphony and the Cathedral Choral Society at the Washington National Cathedral. His summer appearances include the festivals of Grant Park, Boston University Tanglewood Institute, Tanglewood with the Boston Pops, Chautauqua, Sun Valley, Shippensburg, Bravo Vail Valley, the Kinhaven Music School and the Performing Arts Institute (PA).

As a self-described “Star Wars geek” and film music enthusiast, Loh has conducted numerous sold-out John Williams and film music tribute concerts. Part of his appeal is his ability to serve as both host and conductor. “It is his enthusiasm for Williams' music and the films for which it was written that is Loh's great strength in this program. A fan's enthusiasm drives his performances in broad strokes and details and fills his speaking to the audience with irresistible appeal. He used no cue cards. One felt he could speak at filibuster length on Williams' music.” (Pittsburgh Tribune)

Mr Loh has assisted John Williams on multiple occasions and has worked with a wide range of pops artists from Chris Botti and Ann Hampton Callaway to Jason Alexander and Idina Menzel. As one of the most requested conductors for conducting Films in Concert, Loh has led Black Panther, Star Wars (Episodes 4-6), Jaws, Nightmare Before Christmas, Jurassic Park, Casablanca, The Wizard of Oz and Singin’ in the Rain, among other film productions.

Lawrence Loh received his Artist Diploma in Orchestral Conducting from Yale, his Masters in Choral Conducting from Indiana University and his Bachelor of Arts from the University of Rochester. Lawrence Loh was born in southern California of Korean parentage and raised in Carlisle, Pennsylvania. He and his wife Jennifer have a son, Charlie, and a daughter, Hilary.

Now celebrating its 60th anniversary season, the 80+ member Grant Park Chorus was formed in 1962 by Thomas Peck, who led the group until his death in 1994. His protégé, Michael Cullen, then led the chorus until 1997, after which a series of guest conductors worked with the ensemble until 2002 when an international search identified current chorus director, Christopher Bell. 

Winners of the 2006 Margaret Hillis Award for artistic excellence, the Grant Park Chorus is a fully professional ensemble and the majority of the vocalists reside in Illinois. In addition to frequent solo appearances and teaching careers, members of the Grant Park Chorus perform with ensembles such as Chicago a cappella, Lyric Opera of Chicago, and the Chicago Symphony Chorus.
