4ZZZ is an independent community radio station which began transmission in Brisbane in December 1975. It was the first community FM broadcaster in Queensland and the first in Australia to pioneer the playing of contemporary Australian music. During the 1980s and 1990s, Market Day was an annual outdoor festival and fundraising event, which featured local live music. Local punk band Mystery of Sixes supported the touring American band Dead Kennedys in Brisbane in 1983.
