This fourteen-member group from the California Central Valley performs on five octaves of Malmark handbells and five plus octaves of Malmark hand chimes. Opus has been featured guest artists for several community concert series and has rung with the Modesto Symphony Orchestra. They have shared this unique instrument and their music locally, nationally, and internationally, from Modesto, California, to Las Vegas, Nevada, to Coventry, England, in the United Kingdom.

This program is included with regular museum admission.
