The Diamond Dogs Tour was a concert tour by the English singer-songwriter David Bowie in North America in 1974 to promote the studio album Diamond Dogs (1974). The first leg of the tour utilized a rock opera-style stage show format with multiple sets, costume changes and choreography. The remainder of the tour was alternatively known as The Soul Tour, which included some songs from the forthcoming album Young Americans (1975) and featured a revamped, stripped-down presentation and different backing band.

The Sound+Vision Tour was a 1990 concert tour by the English musician David Bowie that was billed as a greatest hits tour in which Bowie would retire his back catalogue of hit songs from live performance. The tour opened at the Colisée de Québec in Quebec City, Canada on 4 March 1990 before reaching its conclusion at the River Plate Stadium in Buenos Aires, Argentina on 29 September 1990, spanning five continents in seven months. The concert tour surpassed Bowie's previous Serious Moonlight (1983) and Glass Spider (1987) tours' statistics by visiting 27 countries with 108 performances.
