Apollo Chorus of Chicago
Founded shortly after the Great Chicago Fire in 1872 as the "Apollo Music Club", it is the oldest volunteer choir in the United States. The ensemble performs Handel's Messiah every year, and has since the year 1879. They released a recording of the complete Messiah in 2006.
In addition to Messiah, the Chorus performs other works such as Verdi's Requiem, Karl Orff's Carmina Burana, and Bach's Mass in B Minor. The group also performs numerous community events in the Chicagoland area.
