NMC has appeared in the concert series at Waterford, Va., and locally in a variety of locations, including the George Washington National Masonic Memorial in Alexandria. There, the chorus presented a collection of the "Masonic Music" of W. A. Mozart together with Randall Thompson's Testament of Freedom, with full orchestra. The Washington Post characterized the music as "superbly styled" and reported that the Chorus "...sang with smooth, well-blended tone, emotional conviction and a clarity of diction that was a pure joy."

The Chorus has been honored with prestigious concert invitations, including the American Music Festival at the National Gallery of Art. At the dedication of the George Mason Memorial near the Washington Mall in the spring of 2002, National Men's Chorus performed the cantata, Life and Liberty, a Thomas Beveridge setting of texts by George Mason commissioned for the occasion.

NMC has appeared twice at the Rachel M. Schlesinger Concert Hall and Arts Center, most recently with the Alexandria Symphony.  The chorus has developed a wide-ranging repertoire of American patriotic music, some traditional, some historic and seldom-heard.  Much of that music is available on the recently released CD "Life and Liberty" featuring the Washington Symphonic Brass and organist Paul Skevington.
