The Oregon Symphony, based in Portland, Oregon, was founded in 1896 as the Portland Symphony Society; it is the sixth oldest orchestra in the United States (and the oldest in the Western United States),[1] and claims to be one of the largest arts organizations in the Pacific Northwest.

In 1992, the orchestra released its first record through Koch,[5] with works by Gian Carlo Menotti, Ronald Lo Presti and Norman Dello Joio.

DePreist and the Symphony then issued two special edition albums not available commercially: Romeo and Juliet (1992), featuring Tchaikovsky's Fantasy Overture Romeo and Juliet, and Roman Festivals (1993), a re-issue of the performance of Respighi's Feste Romane from Bravura.

On Martin Luther King, Jr. Day in 1995, the Symphony released its second album through Koch, with works by Joseph Schwantner and Nicolas Flagello; more than 30 United States radio stations broadcast Schwantner's piece on the holiday to commemorate the civil rights leader.
