Kim's arrangements for orchestra have been performed by the Atlanta, Baltimore, Boston, Boston Pops, Cleveland, Hollywood Bowl, Houston, Minnesota, National, Pacific, Philadelphia, Rochester and St. Louis Symphony Orchestras as well as many others. In February 2003 he was the guest speaker at the American Symphony Orchestra League conference in New York City where he talked about arranging for Pops orchestras.
Kim has guest conducted the Minnesota Orchestra and the Atlanta Symphony in addition to hundreds of recording sessions with orchestras in Los Angeles, New York, Washington D.C. and London. Kim co-produced, arranged and conducted the orchestra for Linda Eder's song Gold which was featured in the opening ceremonies for the 2002 Winter Olympics.
The Atlanta Symphony Orchestra continues to perform Kim's arrangements with Earl Klugh, Big Bad Voodoo Daddy, Sister Hazel, Edwin McCain and Celtic rock band Seven Nations. He arranged a theme song penned by hip hop producer Dallas Austin (Madonna, TLC, Boyz II Men) for the city of Atlanta that featured the symphony and was recorded by Deutsche Grammophon. In 2009 Kim also arranged and recorded the Atlanta Braves "Tomahawk Chop" for the orchestra.
His work has also been a part of the Boston Pops television specials on the 4th of July - in 2002 on A&E with Linda Eder and in 2003 on CBS with LeAnn Rimes singing two songs including Kim's new arrangement of America the Beautiful which also featured the 360 voice Mormon Tabernacle Choir. On New Year's Eve 2003 the Pops played eight of his arrangements featuring 15-year-old vocalist Kaitlyn Lusk who he is also producing. That May Kaitlyn returned to Symphony Hall for two sold out concerts where she sang Kim's new arrangements of songs originally made famous by Judy Garland.
Two current projects are FilmSong with Kaitlyn featuring new and classic movie songs and Handel's Messiah Rocks, a new version of the holiday favorite featuring three amazing singers, Keith Lockhart, the Boston Pops and a rocking band. The production has been shown on PBS and toured nationally.
