In Search of Sunrise 6: Ibiza (also known as ISOS 6) is the sixth album in the In Search of Sunrise series mixed by trance DJ/producer Tiësto, released on September 7, 2007 in the Netherlands and October 16, 2007 in the United States as a double disc album. This information was confirmed on July 31, 2007 on Tiësto's website. Many file-sharing websites, earlier in 2007, released a fake torrent of In Search of Sunrise 6, labeled In Search of Sunrise 6 - London, which even included a CD cover. This was quickly noted as a fake as information of the CD had not been released via Tiësto's website nor the In Search of Sunrise series website. A special release party was held at the Heineken Music Hall in Amsterdam on November 3, 2007. Like previous In Search of Sunrise albums, this album contains a special slipcase. The album picture was taken by Stephanie Pistel. The compilation was awarded in the 2008 WMC Awards in Miami, it won for "Best Full Length DJ Mix CD".
Inspiration to produce this album came from returning to Ibiza after a two-year stint in June 2007. This album was produced in 2007 during the summer time the old-fashioned way as Tiësto stated on his website. Tiësto used CD mixers and did not use any programs or computer gadgets. Tiësto also stated on his website on August 13, 2007, "Most of the tracks are so exclusive that, if I'd still be mixing with records, I wouldn't have been able to get those productions on vinyl!" On August 17, 2007 on Tiësto's MySpace blog, a thirty-second promotional video was released on YouTube.
On August 15 and 25th, two samplers exclusive to Beatport were released with four songs each. On August 29, 2007, Tiësto released a limited edition vinyl sampler that included all 8 songs from the first two samplers, which was made available online, a third sampler was released in Netherlands as a CD.
