OST Oklahoma! 75th Anniversary

A groundbreaking "integrated" show that ushered in a new era in Broadway musicals, Oklahoma! also holds the unique distinction of having been the first stage production to spawn an original cast album. Upon its release on December 2, 1943, the recording became an instant success, paving the way to a new musical genre, the "Broadway cast album," that has been flourishing ever since, and changing the way the theatrical and music industries intermingle.
