The group was founded in 1971 and disbanded in 1993. David Cran (trumpet) and Robert Posten (bass trombone) remained with the group for the duration through various personnel changes. It was the first American brass quintet to serve as the full-time and exclusive professional occupation of its members. The group toured extensively in the United States (New York debut, 21 January 1984), Canada, Europe, and Asia; they also became mainstays at music festivals and music camps worldwide. The group played a major role in developing brass quintet literature through editions of Renaissance and Baroque music and an active commissioning program; it gave over 75 premieres, including works by George Walker, Robert Starer, Lawrence Moss, and Jiri LaBurda. In 1979 the ensemble organized the Brass Chamber Music Society of Annapolis, and in 1980 it established the International Brass Quintet Festival in Baltimore, to bring together professionals from both Europe and the United States with student ensembles for brass performance and study.
