On March 14, 2004, the Claremont Symphony Orchestra presented a very special concert with Spectrum, a vocal quartet dedicated to keeping Motown and R&B favorites alive. Spectrum has since returned to Claremont to perform with the CSO twice, most recently on June 9, 2013.

On October 16, 2022, the Claremont Symphony Orchestra was excited to return to the stage after a nearly three-year hiatus, due to the COVID-19 pandemic. Below is CSO's performance of Dvorak's New World Symphony.
