The Saturday evening concert will begin the Woodland Chamber Singers, an accomplished, versatile chorus that has been charming audiences in Yolo County, not to mention the Carnegie Hall audience that saw them perform two years ago. A concert in San Andreas or Douglas Flat or Murphys to hear the Mountain Melody Women’s Chorus? You will want to go, once you have heard this crowd-pleasing group on the SacSings stage. Then there are the Reconciliation Singers Voices of Peace (RSVP). They have built a reputation in our area for supporting charities, but it’s their exquisitely refined sound and vocal energy that will awe this evening’s audience. Next the Valley Choral Society will provide a change of pace with what they do so well, presenting a stirring set of light classical music. And for a climax to this very diverse concert, we will look to the the Sacramento Gay Men’s Chorus, who never fail to dazzle their audiences with their humor, choralography, and solid 4-part harmony.
