The UConn Collegium Musicum, a group of musicians who specialize in music from the 17th and 18th centuries, will perform Reinhard Keiser’s “Brockes-Passion” on Sunday, Feb. 12 at 3 p.m. at St. Mary’s Church 46 Valley St., Willimantic.

A Passion oratorio is an extended musical work with soloists, chorus and orchestra describing the suffering of Jesus at the Crucifixion. The composer of the work, Keiser, was a contemporary of J.S. Bach, and Barthold Heinrich Brockes wrote the libretto. This concert, which include professional musicians, will very likely be a North American premiere of the piece.

The UConn Collegium Musicum consists of approximately 16 singers and 15 instrumentalists and its purpose is to promote an understanding of the music of the late Middle Ages, Renaissance, and Baroque period with regard to style, performance practices. The performance features period instruments from the university’s extensive collection of early instrument. Membership in the group is open to current students, alumni, faculty, and community members.

Admission to the concert is free. The concert is made possible by a grant from the Paul C. Richards and Gladys Richards Charitable Foundation. For more information go to: music.uconn.edu
