 The Minnesota Orchestra dates back to 1903 when it was founded as the Minneapolis Symphony Orchestra . It was renamed the Minnesota Orchestra in 1968 and moved into its own building , Orchestra Hall , in downtown Minneapolis in 1974 . The building has a modern look with a brick , glass , and steel exterior , in contrast to the old @-@ world look of traditional concert halls . The interior of the building features more than 100 large cubes that deflect sound and provide excellent acoustics . Later the Saint Paul Chamber Orchestra became the second full @-@ time professional orchestral ensemble in the cities .
