The ability to capture groups of musicians in the more spacious studios of the electrical recording era (not to mention in music halls or other places where music was traditionally performed) led to another new variety of record: the live recording. Many performances broadcast live on radio in the 1930s were also recorded, usually for the purpose of re-broadcast later. During World War II, these recordings were captured in large numbers, recorded on special discs, and sent overseas to entertain the troops. A few of these performances eventually made their way onto consumer discs. Some of the “classic” early live recordings were made by Glen Miller and his orchestra in the late 1930s, one in Carnegie Hall and another in an auditorium at Asbury Park, New Jersey. These records established the model for the live recording, which included audience sounds, the commentary of the performers, and often improvisational performances.
