Dusty Cowpoke is performance artist who jumps and rolls around mimicking the movements of a cowboy in a shootout, and uses his hands that acts like a Revolver. The theme of this show takes place in a western-style desert with a classical country music. The audience disliked his performance, most likely because his entertainment is much less appealing. He is only seen in the first act in the game.
If you listen closely to the music Dusty is performing to, you will notice it is the exact same music hear from the Redwood Cigarettes commercial heard on the radio stations in Grand Theft Auto: San Andreas. He is voiced by Matt Williams.
