Every Thursday a committed group of students stand around a piano and sing.  Started by juniors Anna Biggs and Nissa Rolf, the group is called A cappella.  “I’m there to support them, but they’re really doing it themselves,” Upper School choir director and the group’s advisor, Anne Klus said.  The group is off to a brisk start as they were already singing around the piano together during the first practice. With a good turnout of students from the beginning,  A cappella includes both upperclassmen and underclassmen. The members of the group and Klus hope to perform at assemblies and other venues throughout the year.
