System of a Down and Slipknot aren't just playing for their loyal fans this fall — they've named the tour in honor of their fans' dedication.

The Pledge of Allegiance tour, which the two bands will co-headline, will run for six weeks, kicking off at the Thomas & Mack Center in Las Vegas on October 1, according to the trek's publicity firm, Scoop Marketing.

Stone Temple Pilots singer Scott Weiland said last week that System of a Down were in discussions to appear alongside STP and Staind on the Family Values tour, also slated for the fall. System of a Down's publicist said the band had considered Family Values along with other touring options, but decided to stage its own outing instead.

In addition to the main stage, the trek will feature new artists on a second stage, along with other entertainment, according to Scoop. A complete itinerary and talent lineup is expected soon. System of a Down and Slipknot are among the partners in the tour, which they plan to stage annually.

System of a Down are wrapping up work on the follow-up to their self-titled debut, due this summer.

Slipknot's as-yet-untitled second album is due July 17. The band recently canceled a string of concerts that were to kick off this week.
