On Friday, experimental pop ensemble Beauty Pill played our quarterly Luce Unplugged Community Showcase at the Smithsonian American Art Museum, but with a special twist: It was accompanied by a four-piece horn section. It was a rare treat for those in attendance, but not as unprecedented as it may seem. “This was always a possibility,” said drummer Devin Ocampo. “The guy who arranged the horns on the record based it on Chad [Clark’s] template. We wanted to do something special for this event. If we had the money we’d always have a horn section.” With an audience full of people of all ages, the band played both old and new songs. A horn section always make music swing a little more, and Beauty Pill’s new stuff was no exception.
