Tool are, of course, riding high on the success of Fear Inoculum, their triumphant first album in 13 years. The reviews have largely been positive, and commercially, the record not only marked the group's third consecutive No. 1 debut in the U.S. — where they knocked Taylor Swift out of the top spot — but it also tallied the best first week for a rock album in over a year. The band has big tour plans in support of the LP, including a North American run with Killing Joke set for this fall, but after that, the big question looms: Will there be another Tool album and how long will fans have to wait for it?

Asked by Metal Hammer what the future holds for the group, drummer Danny Carey was circumspect, as the band members tend to be in interviews, but also positive about the prospects of a follow-up record. "My hope is we get in and knock out another record," he said. "We have tons of material. It's not going to take 12 years, or if it does, I'll probably be so old I probably can't pick up my sticks any more! But my hope is we'll do another record and just keep moving forward."

"There are no leftover Tool songs because of the process it takes to compose our songs," Carey clarified. "The way we hash it out in a room with all three or four of us, that there's tons of riffs and jams and things. But there's no put-together songs that are sitting in the eaves.

"It'll take a process of doing it. And if we do do another album, it'll take three years after touring. That's just the way it is with our band."
