Launch Radio Networks reports: TOOL will return for another North American tour in March and April, according to drummer Danny Carey, who also told Launch that the band's stage show on its next trek will be different from what audiences saw this summer and fall: "The show in the springtime will definitely be different than the shows that went around this fall in America. Projection ideas will be added and changed, and props and whatnot will all evolve too, I'm sure. You know, it's just the way our band always works. We work on that kind of thing all the time."No dates or cities have been revealed yet for the band's next American jaunt. TOOL continues to tour in support of its fourth studio album, "10,000 Days", which has sold more than 1.2 million copies since its release last May. The CD's latest single is "The Pot". The group begins a European trip on Saturday (November 4) in Spain. TOOL will headline the annual Big Day Out festival tour of Australia and New Zealand, which begins on January 19. The group will be joined by THE KILLERS, MUSE, MY CHEMICAL ROMANCE and JET on the bill, which will hit at least seven cities in both countries during a two-week stretch.
