INXS (a phonetic play on "in excess") were an Australian rock band, formed as the Farriss Brothers in 1977 in Sydney. The founding members were bassist Garry Gary Beers, main composer and keyboardist Andrew Farriss, drummer Jon Farriss, guitarist Tim Farriss, lead singer and main lyricist Michael Hutchence, and guitarist and saxophonist Kirk Pengilly. For 20 years, INXS was fronted by Hutchence, whose magnetic stage presence made him the focal point of the band. Initially known for their new wave/pop style, the band later developed a harder pub rock style that included funk and dance elements.

In 1984, INXS had their first number-one hit in Australia with "Original Sin". The band achieved international success in the mid-to-late 1980s and early 1990s with the hit albums Listen Like Thieves, Kick, and X, and the singles "What You Need", "Need You Tonight" (the band's only US number-one single), "Devil Inside", "Never Tear Us Apart", "Suicide Blonde" and "New Sensation".

After Hutchence's death on 22 November 1997, INXS made appearances with several guest singers, and toured and recorded with Jon Stevens as lead singer, beginning in 2000. In 2005, members of INXS participated in Rock Star: INXS, a reality television series that culminated in the selection of Canadian J.D. Fortune as their new lead singer. Irish singer-songwriter Ciaran Gribbin replaced Fortune as lead singer in 2011. During a concert on 11 November 2012, INXS stated that the performance would be their last, although they did not announce the band's permanent retirement.

INXS has won six Australian Recording Industry Association (ARIA) awards, including three for "Best Group" in 1987, 1989 and 1992; the band was inducted into the ARIA Hall of Fame in 2001. INXS has sold over 50 million albums worldwide, making them one of Australia's highest selling music acts of all time.
