The Grammy-nominated early music vocal quartet New York Polyphony has released an album of remarkable sacred works from the Spanish renaissance. Entitled Lamentatione (Lamentations), the recording shines light on four composers, including Francisco de Peñalosa and Pedro de Escobar – both of whom helped spark the flowering of polyphony in the 16th century. New York Polyphony's Craig Philips joins us to preview the disc.
