Gigantour is the name of an annual six-week traveling heavy metal music festival organize by Megadeth's Dave Mustaine. The tour was founded in 2005 with dates across North America, and the 2006 and 2007 line-ups also traveled to Australia. The bands appearing at the festival were chosen by Mustaine because he wanted to "put together a festival that consisted of positive bands that play heavy music in a high energy environment." The tour is set as an alternative to tours such as Ozzfest and Hellfest.
