Opera singer Richard Scott explores opera through the prism of various themes. Today: Crowds and Choruses. Richard talks to the dynamic and passionate composer David Lang about his new work for 1,000 voices, Crowd Out, inspired by being in a crowd watching Arsenal F. C. play; and we’ll also be hearing other riotous, bombastic and extraordinary opera choruses and choral pieces from Bach, Gluck, Britten and John Adams.
