Acid jazz: Acid jazz, also known as club jazz, is a musical genre that combines elements of jazz, soul, funk, and disco.  Acid jazz originated in the London club scene of the mid-1980s in the rare groove movement and spread to the US, Japan, Eastern Europe, and Brazil.  Major acts included Brand New Heavies, Incognito, Us3, and Jamiroquai from the UK and Buckshot LeFonque and Digable Planets from the US.  The rise of electronic club music in the mid to late 1990s led to a decline in interest, and in the twenty-first century, the movement became indistinct as a genre.  Many acts that might have been defined as acid jazz are now seen as jazz-funk, neo soul, or jazz rap.

Music on The O.C.: The use of music on FOX drama "The O.C." gained much acclaim.  Show creator Josh Schwartz wanted music to be a "character on the show" and the experienced Alexandra Patsavas took the role of music supervisor.  The show's orchestral music was composed by Christopher Tyng.  The series is credited with showcasing many artists, and helping to elevate them in the music business.  Many acts made guest appearances on the show, and others premiered their new singles in episodes.  Six official soundtracks were released, and these were compilations of predominantly indie music.

The Great Escape (festival): The Great Escape was a music festival held at Newington Armory, located within Sydney Olympic Park that took place in 2006 and 2007.  Initially held over the Easter long weekend for the first two events, in 2008 it was announced the festival would take place on the Labour Day weekend, however the event was cancelled 2 months from the date due to poor ticket sales .  It evolved from the 2005 Cockatoo Island Music Festival.  The music and other attractions run over three full days (Good Friday to Easter Sunday in 2006–07), with some patrons camping from Thursday evening to Monday morning.  Punters could attend either for the full weekend camping, purchase a 3-day pass and commute each day or attend a single day.  Many acts also played the East Coast Blues & Roots Music Festival the same weekend, however The Great Escape line-up is more diverse featuring pop, hip hop, electronic and rock acts that would not fit into a Blues and Roots line-up.  In addition to musical acts, there is also a wide range of other features such as comedy acts, bingo and trivia, conspiracy theory talks and yoga.  There is no immediate future for the Great Escape at this point, but organisers are confident it will be resurrected in the near future.
