Mustang! is the first full-length studio album by Dragon Ash, released on November 21, 1997. Even though chronologically it was already their third commercial release—preceded by two mini-albums (The Day Dragged On and Public Garden) earlier in the year—nevertheless, due to its full-length nature Mustang! is considered as the group's debut album, also marking their first major commercial release into the Japanese music market.
