Pro Pacem (For Peace) consists of twenty-three excerpts from the Alia Vox catalogue, spanning five centuries of music, from Gilles Binchois to Arvo Part. The cover art was designed by Catalan painter Antoni Tapies, shortly before his death in February. The accompanying 1,000-page book features texts by renowned writers, including the French scholar Edgar Morin. This essential collection assembled by maestro Jordi Savall makes an eloquent statement about the world, both as it is and as it should be, and its debt to the power of music.
