The group tours frequently, both domestically and internationally; has been featured on a number of commercial recordings; and has commissioned notable works for men's chorus.
Under his leadership, the Glee Club celebrated its 125th anniversary in 1997 with a performance, in combination with the Rutgers University Orchestra, of Maurice Duruflé's Messe Cum Jubilo before a nearly sold out audience at Lincoln Center's Alice Tully Hall.
The Glee Club completed a successful tour of Eastern Europe in the summer of 1999 with concerts in such venues as the St. Martin's Dome in Bratislava, Slovakia and the Karlskirche in Vienna, Austria.
Under the leadership of "Soup" Walter, the Glee Club performed regularly with the New York Philharmonic and the Philadelphia Orchestra under the batons of such notable directors as Erich Leinsdorf, Leonard Bernstein and Eugene Ormandy.
Recordings from that era include the Glee Club as the men's section in Carl Orff's Carmina Burana (still available on compact disc on Sony's Essential Classics series), and the Grammy-nominated performance of Sir William Walton's Belshazzar's Feast, both conducted by Eugene Ormandy with the Philadelphia Orchestra.
The group has four times performed for conventions of the American Choral Directors Association, in 2001 in San Antonio, in 2005 in New York City, of which included the premiere of a piece by Jennifer Higdon, 2010 in Philadelphia, and in 2017 in Minneapolis.
