Tomás Luis de Victoria's requiem mass for six voices, written in 1603 and published in 1605, is a masterpiece. It is one of a handful of large-scale works which enjoys mainstream appeal in the 21st century. For many, it represents what Renaissance polyphony is, what it sounds and feels like, and how expressive it can be. The album also features two well-known works by Victoria's contemporary Alonso Lobo.
