Tomales Town Hall will celebrate the reopening of its newly renovated performance stage on Friday with a show featuring the Tomales High School Pan Band and the Hillwilliams. Most of the proceeds will go to support the pan band, which uses over a dozen steel drums for a repertoire that mixes a bit of everything, from traditional Calypso and jazz to heavy metal, rock and Bach. “The beauty of the steel drum ensemble is that it’s adaptable to many genres of music,” said Tami Pallingston, the school’s band director. “It’s a nontraditional music program, but we still teach the basic foundations of music theory, appreciation and reading notation.” Ms. Pallingston reenergized the school’s band program in 2007 with a handful of students playing five-gallon buckets. Today, the band has grown to 30 students, nearly 20 percent of the school’s total population. “Serious fun is what it is,” said Ms. Pallingston. “Students learn how to work collaboratively as a team. They learn confidence. It gives them a sense of belonging.” Followed by the Hillwilliams, a local bluegrass band, the pan band will be the first act to grace the renovated stage. Volunteers have worked off and on to repair the stage since 2008, when the hall received a $50,000 dual grant from the National Trust and American Express. “It was at a point that you could actually fall through the stage floor,” said George Magan, the president of the hall’s board of trustees. “Now we have an extremely well built stage.” Most important among the stage’s many renovations is a 50-by-20 foot concrete foundation. Since 1880, the stage has existed in many forms, but it has never had a foundation. Volunteers also installed one-inch thick foam panels along the sides of the building’s 14 windows to improve the acoustic quality of the space. The grant helped pay for repairs of the building’s walls, floors and stairs, and funded a new curtain, a handicap ramp and stage lights. “The stage had been in pretty dire straits for a long time,” Mr. Magan said. “Now it’s in better shape than the rest of the building.” While stripping away sheetrock from the back wall of the stage, volunteers discovered a large painted mural that showed advertisements of past high school plays and bore signatures from students from as far back as the 1920s; included among the signatures was that of Hazel Martinelli, the late matriarch of West Marin’s Martinelli family. “Two Bands on a New Stage” takes place this Friday at 7 p.m. at the Tomales Town Hall.
