Interviews and recitals of the Chestnut Brass Company have been featured on National Public Radio's All Things Considered, Fresh Air, Radiotimes and Performance Today programs; Voice of America, Radio Free Europe, Bavarian State Radio and numerous radio and television stations across the United States. The Chestnut Brass Company has been featured in performance at the Juilliard School, the Chautauqua Institute, the Ambassador Series of Los Angeles, the Boston Museum of Art, Merkin Concert Hall, Alice Tully Hall and the Yale Collection of Instruments. As curators of the sounds of ancient and antique brasses, the Chestnut Brass Company have been at the forefront of the period-instrument revival with performances on cornetti, sackbuts, keyed bugles and saxhorns. The quintet continues to collect antique brass instruments and to research the literature and performance practice of these instruments.

Their educational program Hot Air: the Story of Brass Instruments was one of three programs selected by the Kennedy Center for the Arts for a live web broadcast. The program was renewed for inclusion on the Kennedy Center website. The CBC can be heard on the Sony, Newport Classic, Crystal and Musical Heritage/Musicmasters labels. Selections from CBC recordings have been included on several documentaries ranging from A House Divided for PBS, to Pinehurst, the History of Golf.
