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, 2011, the Claremont Symphony Orchestra was proud to present local favorite Maria Perez-Goodman in a virtuoso performance of Chopin's 1st Piano Concerto. The 2nd movement is shown in this video clip.
