A Reality Tour was a worldwide concert tour by the English singer-songwriter David Bowie in support of his 2003 album Reality. The tour began on 7 October 2003 at the Forum Copenhagen, Denmark, continuing through Europe, North America, Asia, including a return to New Zealand and Australia for the first time since the 1987 Glass Spider Tour. At over 110 shows, the tour was the longest tour of Bowie's career. A heart attack in late June 2004 forced the cancellation of some dates near the end of the tour. Bowie retired from performing live in 2006, making this tour his last.
