A Contemporary Sacred Manifesto
What does it mean to write with blood?
Twenty-five years in the making, Missa Ad Astra is a contemporary mass unlike any other. Composer Rui Paulo Teixeira and writer Alvaro Aspera didn't simply create new settings of traditional texts. They made a sacred promise to themselves: to "write with blood" – to write only what they had lived, what they had earned through experience, what had become undeniably true.
Each movement waited to be born until its truth had been lived.
Traditional in structure, revolutionary in spirit.
Entirely new Latin texts. Original music for SATB soloists, mixed choir with water-tuned glasses, and orchestra with basso continuo. Also on period instruments. 25 minutes duration.

Rui Paulo Teixeira writes with a truly silken hand that goes directly to the interior of each person... He truly manages to bring out the best in us through this music.

This is more than an exercise: it is a Work of Art. This work restores our sense of wonder before the Mystery.

The decision to compose a Mass demonstrates a desire to provide, beyond musical enjoyment, a spiritual experience – beyond the routines and hustle of everyday life.

We are touching souls, in an act of unprecedented modernity.
