In 1991, the band received its current name and was assigned to Electronics Systems Center, Hanscom Air Force Base, in Massachusetts.

The band performs around four hundred engagements a year, and has appeared at such venues as Lincoln Center in New York City and the Hatch Shell in Boston.

On 20 January 2009, the Band of Liberty's Colonial Brass provided musical support at the Farewell Ceremony of President George W. Bush.
