(BH Secular Choral). The Lost Birds is a musical memorial to bird species driven to extinction by humankind. Sweeping and elegaic, it's a haunting tribute to those soaring flocks that once filled our skies, but whose songs have since been silenced. It's a celebration of their feathered beauty: their symbolism as messengers of hope, peace, and renewal. But it's also a warning about our own tenuous existence on the planet: that the fate that befell those once soaring flocks foreshadows our own extinction.
