With an established choral tradition spanning eight decades, the Cliff Singers have consistently been lauded at public performances in local, regional, national, and international venues.  An auditioned ensemble open to every member of the university community, the seventy-voice Cliff Singers perform a wide variety of choral music from the finest traditions of Western historical music through ethnic and world music embracing all genres.  In addition to their regular concert series through the Music Department, the Cliff Singers sing at university and civic events, including frequent performances with the Sioux City Symphony Orchestra.

Over the years, the Cliff Singers have been selected for performance at state, regional and national conferences of the American Choral Directors Association (ACDA) and MENC:  The National Association for Music Education.  The Cliff Singers tour annually and have concertized throughout the United States, Canada, Mexico, and Europe.   A sampling of recent achievements includes joint-concerts, collaborations and/or projects with the Nebraska Choral Arts Society, Sioux City Symphony Orchestra, Siouxland Choral Artists, Una Vocis, Clarke College, Graceland University, University of Hawaii at Manoa, University of Nebraska at Omaha, Iowa Central Community College, Kapiolani Community College, Western Iowa Tech Community College, Bishop Garrigan High School, Bishop Heelan High School, Lewis Central High School, Sioux Center High School, Spencer High School, First Presbyterian Church of Sioux City, Grace United Methodist Church of Sioux City, Morningside Lutheran Church of Sioux City, Mt. St. Francis Dubuque, Mt.
