This is one of my favorite carols, in part because of how "the 'o' of 'Gloria' is fluidly sustained through 16 notes of a rising and falling melismatic melodic sequence" (Wikipedia). It is based on a French traditional carol and on the nativity story in Luke 2:1-20. In the clip above an arrangement by Mack Wilberg is performed brilliantly by the Portland (Oregon) Choir and Orchestra, conducted by David M. Thomas and featuring soprano soloist Emily Thomas.
