Nebraska's Professional Chorale, is the product of the creative imagination of Almeda and Jackson Berkey, performing artists of Mannheim Steamroller fame. For years the Berkeys envisioned a choral group versatile in many styles of music and comfortable in a variety of performance and recording settings. The Cantorum's fulfillment of that vision has surpassed even their own expectations. The inspiration that led to forming the 28-member group can be traced not only to the Berkeys' sense of devotion to music, but to the influence of the late Norman Luboff as well. Almeda and Jackson Berkey met prior to a national tour with the famed Luboff choir -- Almeda as a singer, Jackson as a tour pianist. This combination of rare talents has lifted their musical accomplishments to heights which neither could have achieved individually.
