Penn State Behrend's 17th annual Tuba Christmas concert drew a large crowd to McGarvey Commons, in the college's Reed Union Building. The holiday concert is a showcase for low-brass musicians -- many of whom wore pajamas. "Low-brass players tend to have a good sense of humor and a real love of what they do," said Gary Viebranz, director of instrumental ensembles at the college. "There's a real camaraderie there."
