Old and New Worlds is the result of an international collaboration between Ars Veritas (Gothenburg, Sweden) and Schola Cantorum (Miami University, Oxford, Ohio). It features great choral works of the past and the present. Ensemble Ars Veritas started in 2010 at the University of Stage and Music in Gothenburg. Jakob Patriksson led the work on creating an ensemble focusing on early church music and the sacred music it later inspired. One of the hallmarks of Ars Veritas is the concerts that gradually illustrate the evolution of Western European church music: from the sacred unanimous Gregorian music to the first completely independent polyphonic works.
