The Impossible Music Festival was a recurring event broadcast on Australia's Triple J radio station over 55-hour periods in 2005, 2006, 2007 and 2008.
The first went to air over 26–29 August 2005, to celebrate the 30 years worth of live music recorded by Triple J.
The recordings included music from festivals, concerts, smaller pub gigs, bands playing live in the studio, and some special events where listeners were able to win tickets to see the band for free in a secret location.
One live set was played every hour between 6 pm on Friday 26th, and 1 am on Monday 29 August.
The following is the order in which the broadcasts went to air; the details in the brackets denotes the location and date in which the live recording was made.
