When the American Brass Quintet gave its first public performance on December 11, 1960, brass chamber music was still relatively young to concert audiences. American Brass Quintet dedicated itself to "music originally written for brass," and substituted a bass trombone for the conventional tuba voice. That debut concert for them in 1960 marked the beginning of an international career for the ensemble that includes performances in Europe, Central and South America, the Middle East, Asia, Australia and all fifty of the United States; a discography now numbering fifty-one recordings; the premieres of over one hundred new brass works, and the inspiration to a whole new generation of brass quintets worldwide. ABQ commissions by Samuel Adler, Bruce Adolphe, Daniel Asia, Jan Bach, Robert Beaser, William Bolcom, Elliott Carter, Billy Childs, Robert Dennis, Jacob Druckman, Eric Ewazen, Anthony Plog, Huang Ruo, David Sampson, Gunther Schuller, William Schuman, Ralph Shapey, Joan Tower, Melinda Wagner, and Charles Whittenberg are considered among the most significant contributions to the brass quintet repertoire. In the past fifteen years alone, the ABQ has released recordings of over twenty-five major new brass quintets. The presentation of challenging contemporary brass music alongside earlier eras carefully edited by ABQ members for modern performance, has become a trademark of ABQ programming, and has helped establish the American Brass Quintet as the leader in the field of serious brass chamber music today.
