Since the formation of Alien Ant Farm in 1995, the quartet has enjoyed worldwide success. Over the course of their four studio albums, cumulative sales surpass five million units. In 2002, fame spread across the world, bringing Alien Ant Farm to the major European festivals, Australia's Big Day Out, and a headline run in Japan. The following year they returned to Europe with Metallica, and to this day the band has steadily delivered audiences in territories across the globe.
