The first professional chorus to have its own regular nationally syndicated radio series (broadcast over the WFMT Fine Arts Network and heard on the BBC, CBC, and European Broadcast Union), they've performed at Lincoln Center, the White House, the Library of Congress, and Ravinia, and perform a series of nearly 30 local concerts annually in several of the Chicagoland area's significant sanctuaries.
Founder Thomas Wikman, a distinguished conductor, organist, harpsichoridist and pianist, has conducted every performance of the group through its 24-year history. When he moved to Hyde Park in 1968 to become the Church of St. Paul and the Redeemer's organist/choirmaster, a number of his vocal students came along (he offered them free lessons if they would perform in his choir). The free lessons attracted a number of other vocalists to the group, and after a couple of successful Bach concerts, the group began expanding both repertoire and performance schedule.

A number of the groups soloists (including Isola Jones, Judith Nelson, Judith Malafronte, Sharon Powell, William Wahman, Arthur Berg, Richard Versalle, Barbara Pearson, Linda Mabbs, Everett Zlatoff-Mirsky, Ray Still, Adolf Hirseth, Grover Schiltz, and Elliot Golub (the longtime concertmaster), were already well-known and/or headed for successful careers in opera or orchestra.

The ensemble's recordings include Mozart's "Great" Mass in C Minor, Telemann's Day of Judgement, and Monteverdi's Vespers of the Blessed Virgin (the latter two both 2 CD sets).
