Acústico MTV: Bandas Gaúchas was a project by MTV Brasil, which brought together the bands Bidê ou Balde, Cachorro Grande, Ultramen and the singer Wander Wildner (former leader of the Replicantes) in a single show, broadcast on TV and released on CD and DVD. in 2005. It was an innovative project, as it brought together 4 artists in a single acoustic and, for the first time, used a pre-defined theme: rock gaucho. The main idea of the project (several bands of the same genre in a single project) was repeated in the MTV Ao Vivo 5 Bandas de Rock project, which brought together 5 pop rock and emocore bands in the same show.
