The choir performs a wide range of works from all time periods and languages, although over the years a special emphasis has been placed on contemporary music of the Americas.
In October 1988, ORS completed a four compact disc contract with Koch International Classics to record new American music.
An excerpt from the 1995 Glory of Christmas concert broadcast on NPR's Performance Today was so well-received that two hour-long specials on ORS followed.
In 2018, ORS released "Shadows on the Stars" with Gothic Records, an album featuring the music of Pacific Northwest composers, including among others Morten Lauridsen.
The album earned the group the America Prize in Choral Performance for the community chorus division.
