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, which was released the same year. The first leg of the tour utilized a rock opera-style stage show format with multiple sets, costume changes, and choreography. The third leg 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.
