Crepusculum, a chamber choir made up of students from Berklee College of Music in Boston, MA, USA, has produced a music video of a piece by local composer Andrew Cusworth.

'Drop down, ye heavens' became the first of Andrew's pieces to cross the Atlantic to America after he met the choir's director and manager Xann Schwinn earlier this year.

The choir released the finished product on YouTube last week - appropriately, just in time for Christmas!
