ENSEMBLE ALTERA is fast becoming a leading American chamber choir dedicated to bringing thoughtful, engaging, and relevant programs of choral music to in-person and digital audiences at home and around the world. The group is versatile, working on multiple scales, in a wide range of idioms, across the full gamut of medieval to modern to minimalist music. Led by internationally acclaimed countertenor Christopher Lowrey, Altera comes from the Italian word for change, and the ensemble prides itself in its truly transformative approach to music-making. Recent projects undertaken by the group include an innovative series of digital concerts recorded in empty parking garages during the Covid pandemic, as well a virtual series of Christmas concerts produced for viewers around the world.


Altera has developed a reputation with audiences for bold programming that invites listeners to imagine connections between works from many different historical perspectives to tell one unified and edifying story. Some of these projects include ‘illumine’, centering on the myriad representations of light across the repertoire, ‘Hail Mary’, a concert based on Marian themes, and ‘Music For Elizabeth’, a program devoted to music heard in Elizabeth I's court. This summer, Altera will mount a Covid Memorial Project entitled 'We Remember', featuring music to uplift, heal, and bring together the community in the wake of the ongoing Covid crisis. As part of this project, the ensemble is sponsoring a Composition Competition for new choral works. Details can be found on the 'Competition' page.

Ensemble Altera is dedicated to the mission of bringing to both the local and global community a greater awareness of and engagement with choral music and group singing in all its forms. This will principally take the shape of presenting physical and virtual concerts, recording audio and video albums, performing educational outreach in settings such as schools, conferences, and broadcasts, touring throughout the United States and further afield, all in service of not only raising the standards of execution and understanding among artists, but more generally advocating for greater exposure to and appreciation for the indispensable and ennobling beauty of the choral arts.
