A. Dennis Sparger
A. Dennis Sparger, MUSIC DIRECTOR AND CONDUCTOR of the Bach Society of Saint Louis since 1986, has earned critical acclaim as “a conductor equipped with insight as well as craftsmanship.” Under his direction the Chorus has been labeled as “right up there with the best this city has to offer.”
His performance of Bach's Mass in B minor was described as “elegant,” and Haydn's Creation was “in perfect balance.” The St. Louis premiere of Berlioz' rediscovered Messe solennelle was hailed “a landmark event” and Rachmaninoff's Vespers, sung in Russian at the Cathedral Basilica, was reviewed as “sublime, lingering in the far reaches of the building like so many gorgeous sunsets.”
During his tenure, Dr. Sparger has led the Bach Society Chorus in over 70 performances of the major works by Bach and other composers, including Handel, Mozart, Beethoven, Berlioz, Brahms, and Rachmaninoff. Performances have included established soloists Christine Brewer, Susan Graham, Kristine Jepson, Erie Mills, Phyllis Pancella and William Warfield, and have nurtured outstanding young singers Thomas Barrett, Rochelle Ellis, Kristen Frost, Angela Horn, Lester Lynch and Mary Wilson.
Under Dr. Sparger's leadership, the Bach Society introduced a Young Artists scholarship program for singers under the age of thirty; the awards have provided financial support and solo opportunities for 38 aspiring soloists to date. He also established a professional core of paid Principal Singers, elevating the performance level of the Bach Society Chorus and bringing employment opportunities for trained choral singers. Upon his recommendation, the Board of Directors designated a position for Composer-in-Residence to promote the creation of new works to be premiered by the Bach Society Chorus.
Dr. Sparger received his professional training from the University of Illinois where he studied with Harold Decker and, in 1981, was awarded a Doctor of Musical Arts degree in choral conducting. He received a Bachelor of Science in Education degree in music and a Master of Arts degree in music history and literature at Eastern Illinois University, where he studied choral music with John Maharg. 
In 1998 Dr. Sparger was presented with the prestigious award named for his mentor, the Harold A. Decker Award, by the Illinois chapter of the American Choral Directors Association. He was named Choir Director of the Year by the St. Louis chapter of the American Guild of Organists in 2003, and was honored as one of Eastern Illinois University's 50 Outstanding Graduate Alumni in 2005. In 2008 Dr. Sparger was selected to participate in a Liberty Fund colloquium on Redemption and Human Freedom in Bach's St. Matthew Passion.  He is a member of ACDA, Chorus America and the National Society of Arts & Letters.
He has served as a panelist for both the Illinois Arts Council and the Missouri Arts Council. His scholarly article on the 17th Century Polish composer Andrzej Hakenberger appears in the latest edition of the New Grove Dictionary of Music and Musicians. Following a career in music education, Dr. Sparger now serves a larger constituency as associate producer and writer of JOY!, a weekly program of sacred choral music heard on KFUO-FM CLASSIC 99.
In addition to his outstanding work with the Bach Society Chorus, Dr. Sparger has received recognition as music director and conductor of the Masterworks Chorale in Belleville, Illinois, an organization he founded and conducted from 1974 to 2007. He also founded the Masterworks Children's Chorus and was their conductor from 1985 to 1990.
 Stephen Mager
Stephen Mager, COMPOSER-IN-RESIDENCE, composes in a variety of genres, with a special emphasis on music for the voice, particularly for chorus and orchestra. His works have been performed by such distinguished ensembles as the Cleveland Orchestra and Chorus; VocalEssence, Minnesota; and the Dallas Symphony Chorus.
His full-scale choral symphony, Sinfonia Pastorale, received its St. Louis premiere in 1997 with the Bach Society of Saint Louis, to critical praise: “the music does indeed have a painterly quality to it. The orchestration is complex and colorful, and the music is inclined to linger over beautiful images… [Mager] writes gratefully for the voice…” (St. Louis Post-Dispatch).
In 2004, he was appointed Composer-in-Residence for the Bach Society of Saint Louis, which has since commissioned and premiered several major choral works: The Lamb's High Feast (2005), an Easter choral cycle on Gregorian chants; I saw eternity (2006), a choral fantasia on a Bach chorale, after Henry Vaughan; and in 2008, Missa lucis (“Mass of Light”), for chorus and chamber orchestra. One critic aptly described the Mass as “lushly lyrical” (St. Louis Post-Dispatch).
His Christmas carol settings have also received critical attention: “Mager's settings… went well beyond mere arrangements; the Noël de la Vièrge had a simple dignity and deft orchestral touch that set it above the usual holiday fare” (St. Louis Post-Dispatch). A collection of his carols is featured on the compact disc, Joy for Every Age, recorded in 1998 with the Arcangeli Chamber Chorus. “These excellent carol settings…exhibit a slightly different kind of charm and sophistication that owes much to their more expansive…fully integrated orchestrations… Mager is conscious of mood and meaning and is very good at drawing listeners into the particular character of each carol” (David Vernier, Classicstoday.com).
His opera, Dream of the Pacific, was commissioned and premiered by Opera Theatre of Saint Louis for the bicentennial of the Lewis and Clark expedition (2004). It was subsequently produced by Opera Omaha (2005), Kansas City Lyric Opera (2005), and Washington National Opera (2006). “Mager excels at conveying a wide variety of feelings…all in a musical language that is both lyrical and comprehensible” (Washington Post).
An active choral and opera conductor, Mager completed his master's degree at Indiana University, and later returned there for doctoral studies. His teachers have included Jan Harrington, Julius Herford, Thomas Binkley, Robert Shaw, Margaret Hillis, Robert Porco, Dale Warland, John Poole, and Carmen-Helena Tellèz. Stephen Mager is also an accomplished organist and pianist. His publishers include Oxford University Press and MorningStar Music.
