LAFAYETTE -- For the second year, the springtime tradition of the Concert at the Res will take place on the permanent stage at the Lafayette Reservoir.

Bands from Acalanes High School, Campolindo High School, Stanley Middle School, the Bentley School, Westlake Middle School (Oakland), the Rossmoor Big Band, the Town Hall Troupe from the Lafayette-based theater of the same name, the Lamorinda Theatre Academy, the Stevie Coyle String Ensemble and the Dominant Seven Jazz Ensemble

The 40-by-40-foot stage, on EBMUD-owned land at the reservoir near the children's playground, was built by the Lafayette Rotary Club and the Lafayette Community Foundation, with the cooperation EBMUD. The local groups get to use the water utility-owned stage twice a year for free.

For many years, members of Rotary and other local volunteers built a temporary stage at the reservoir before the concert, and disassembled it afterward. A years-long effort by the two local groups and EBMUD to build the permanent stage bore fruit last year, when the 2012 Concert at the Res opened the new venue.

The annual concert, conceived two decades ago by Rotarian and former Lafayette planning commissioner Dick Holt, is a fundraiser for Lafayette Rotary, raising money to support not only local school music programs, but other local programs including Lafayette-based Trust in Education, which provides educational, economic and health care assistance to villages in Afghanistan; Meals on Wheels; the Food Bank of Contra Costa and Solano; Generations In Jazz; Futures Explored; Hospice; and the LN4 Foundation, as well as Rotary's own scholarship and grant programs. The concert itself is free, but raffle tickets are sold before and during the concert, and refreshments are available for purchase, too. Listeners can also bring their own picnic lunch, and are encouraged to bring chairs and blankets (chairs and shade umbrellas will be available at the concert).
