The Lux CD contains three additional songs that are exclusively available in this format. "Lux" is the fourth studio album from GRAMMY award-winning singer, songwriter and producer Rosalía. It is her most groundbreaking and global release to date - a monumental masterpiece of vision and craftsmanship. The album was recorded with the London Symphonic Orchestra and features female voices such as Björk, Carminho, Estrella Morente, Silvia Pérez Cruz and the choir of Escolania De Montserrat and Orfeó Català. Rosalía explores themes such as female mysticism, transformation and spirituality and draws a line between illusion and loss, faith and self-discovery.
