The news comes on the heels of the announcement of artistic director and founding member Anne Heider's retirement.

The final season includes the world premiere of a work commissioned from Janika Vandervelde, a cabaret-style gala, and performances at the Chorus America conference in Chicago in June. A recording project, begun last fall, will also be completed.

Tamara Schupman, the group's general manager, said in a statement, "Our tenure will end as it began, with remarkable choral repertoire and that wondrous pristine choral sound which so beautifully expresses it."

Countertenor Richard Childress founded Bella Voce in 1982 as His Majestie's Clerkes. The group's repertoire ranges from classic a cappella repertoire to early music from the Americas to new works commissioned from Midwest composers.
