Musikanten Montana (German for "musicians") was formed by Artistic Director Kerry Krebill in 1979 in Bethesda MD, as a project for her masters degree in choral conducting at the Catholic University of America. In its 46 seasons, the ensemble has made thousands of appearances, including DC area concerts at the National Gallery of Art, the Smithsonian Institution, Kennedy Center, and venues in nearby states, as well as over 2 dozen international tours, including Maestra Krebill's 50th birthday celebration singing Monteverdi's Vespers in Venice with the acclaimed ensemble now known as the Venice Baroque Orchestra.

In June of 2004, Maestra Krebill instituted Helena Choral Week in her new home in Montana, inviting singers from the Helena Symphony Chorale, Musikanten and other ensembles to come together in Helena for an intensive week of rehearsals, concerts, classes and private lessons. Building on the success of this project, Musikanten Montana was established as a new choral chamber ensemble in Helena in September of 2004. The new group's first season culminated in two performances, in Helena and Missoula, of Monteverdi's masterpiece, the Vespers of 1610, as part of the Montana Early Music Festival, which the ensemble sponsored. Musikanten Montana continues to produce the Montana Early Music Festival annually, hosting guest Baroque performers from across the US. In addition to Monteverdi's Vespers, repertoire has included major works of Bach and Handel, works by Charpentier, Buxtehude, Schütz, Scarlatti, Valls, Cavalieri, Purcell, Gabrielli and many others.

Besides the Helena Choral Week in June and the spring Montana Early Music Festival, Musikanten Montana sings an annual concert for All Souls, the Advent Lessons and Carols, and other concerts at St. Peter's Episcopal Cathedral. The ensemble also searches out collaborative appearances in the Helena community - in November 2007, the group participated in "Raise the Roof!" - an event celebrating Harper Lee's classic To Kill a Mockingbird, which featured two local actors, the Helena Middle School Voices of Tomorrow and a gospel choir from Great Falls. In August 2009, the ensemble was honored to perform music for "Catch and Release," featuring 4 fly-fisherman on the Boulder River choreographed by Ann Carlson under an American Masterpieces Dance grant from the NEA.

Singers from Musikanten Montana continue to venture to Washington DC and further (including recent tours to the Baltic capitals, Turkey, Vienna, Berlin and Gdansk) to perform with their Washington DC friends. A major celebration of Washington DC composer Russell Woollen's centenary year included multiple concerts in Montana and the DC area.
