Established in 1995, the Orpheus Chamber Singers present a program of choral music that spans the last thousand years. Founding Artistic Director Don Krehbiel brought 24 talented vocalists together to create a choir that has produced many impressive performances, as well as a pair of critically acclaimed recordings. Through its first 15 seasons, OCS had performed nearly 600 works from 22 countries, some dating as far back as the 10th century. But it’s not all ancient. The group also commissions new works as part of its catalogue, giving the chorus a balance of famous favorites and original pieces that make each concert unique. Although OCS only organizes about four or five programs each season, the choir typically performs each twice in a number of churches in and around Dallas.
