'Lost & Found Sound': The Vietnam Tapes of Lance Cpl. Michael A. Baronowski

In 1966, Michael A. Baronowski of Norristown, Penn., took a tape recorder with him into combat in Vietnam. Lance Cpl. Baronowski was in the demilitarized zone when he captured sounds of jokes, songs, bombs, and bullets. He died later that year in an ambush in a village — but not before sending these recordings home.
