SOURCEWORK, based in Boston, Massachusetts, began in 2015 as a collaborative project with the goal of singing music of the late fifteenth and early sixteenth centuries from original notation. We have grown into an international performing ensemble that prepares and performs all music from original sources.

SOURCEWORK has presented multiple programs in Boston, and has conducted three international tours in England and Ireland (2018), Germany and Austria (2021), and Spain (2024-5). We regularly partner with musicological conferences, rare books libraries, and university music departments to enrich and share our scholar-performer approach to the repertoire.

Our recording of the Missa Super octos tonos and other music by Sebastián de Vivanco (c. 1551-1622), in collaboration with La Danserye and Schola Antiqua (Madrid), is scheduled for release from Odradek Records in 2026 on the Cathedralis label (Salamanca, Spain). Our recording of the Missa Inclina Domine of Philippe Rogier (c. 1561-96), a premiere recording for the work, is currently in production.

SOURCEWORK has collaborated with such artists as Joshua Rifkin (The Bach Ensemble/Boston University), Stratton Bull (Cappella Pratensis/Alamire Foundation), and Anne Azéma (The Boston Camerata).
