The Diamond Dogs Tour was a concert tour by 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.
