This period also saw the band perform with numerous well-known artists and composers, many as part of the very successful Freedom Sings concert series that started in 1950 and continued for several years.

Notable musicians included Metropolitan Opera bass Jerome Hines, composers Paul Hindemith and Percy Grainger, and the pianist duo Whittmore and Lowe.

Eddie Fisher, Robert Dini, and Steve Lawrence were very popular during the 1950s, as were harpist Lloyd Lindroth, future Metropolitan Opera tenor George Shirley, and announcer Charles Osgood.

An official Coat of Arms and distinctive uniforms were approved to reflect the band's increasing visibility at events of national significance, including the visit of Emperor Hirohito to Alaska with President Richard Nixon, the United States Bicentennial in 1976, the Lake Placid Winter Olympics 1980, the return of hostages during the Iran Hostage Crisis, the 1982 World's Fair in Knoxville, Tennessee, and the 1984 Olympic Games in Los Angeles.

Under the leadership of Colonel L. Bryan Shelburne, leader and commander (1990–2000), the band continued with performances at the 1990 Economic Summit in Houston, the Desert Storm Victory Parade in New York City, and Reba McEntire's Christmas Special in Nashville.

In December 2002, a ten-piece pop group from the band, dubbed "Downrange", accompanied country musician Darryl Worley, comedian Kathy Griffin, actress Karri Turner, pro wrestler Bradshaw, and two cheerleaders from the Jacksonville Jaguars to Uzbekistan, Kuwait, and Afghanistan as part of a pre-Christmas USO tour in support of Operation Enduring Freedom.
