The holidays are here, and what better way to celebrate than with seasonal songs from some of Boston University’s best a cappella groups? Over the coming days, BU Today will showcase a different group. The performances were recorded at the Castle. A cappella, which means “in the manner of the chapel,” was first used to describe church music composed for unaccompanied voices, and now refers to any vocal music performed without instruments.

In our third installment, the Barbershop Sweethearts perform “Jingle Bells/Let It Snow,” and “White Christmas.”
