The American Music Center is dedicated to building a national community of artists, organizations, and audiences creating, performing, and enjoying new American music. Since its founding in 1939 by composers Marion Bauer, Aaron Copland, Howard Hanson, Harrison Kerr, Otto Luening, and Quincy Porter, AMC has been a leader in providing field-wide advocacy, support, and connection. AMC advocates for the community through NewMusicBox, its award-winning web magazine, and CounterstreamRadio, a 24-hour online station broadcasting music by a broad range of United States composers. AMC supports the community by making grants to composers and ensembles each year, and by offering professional development programs for artists. AMC connects the community with an array of information services designed to facilitate performances, including the AMC Online Library, a vast, searchable database of 45,000 works by American composers; publications compiling opportunities in new music and other information useful to industry professionals; and benefits and services for nearly 2,500 members in all fifty states and around the world.
