Trio Triumvirum, comprising Aaron Lauber (countertenor), Christopher Mueller (tenor), and Erik-Peter Mortensen (baritone), is an ensemble dedicated to medieval sacred vocal music.  Founded in 2008, this dynamic trio blends virtuosity, beauty, and reverence in restoring this remarkable music to life.  

We're pleased and honored to be working with musicologist Ralph Buxton for score preparations.
