Some broadcasts are from open-air concerts and festivals, or smaller pub gigs around the country.
Many are bands that have been invited into the Triple J studios to play a live set of tracks, usually acoustic.
Occasionally, Triple J will give away tickets to listeners, to allow them to be a part of a special live performance in a secret location.
Many complete live sets are traded by music fans worldwide over the internet.
Live music is not exclusive to the Live at the Wireless segment - many other shows, including the specialty music shows, also have bands playing acoustic in the studio.
