Tool bassist Justin Chancellor has provided an update into the band’s famously-protracted album release schedule, revealing that the Los Angeles quartet will be hitting the studio following their upcoming tour of South America.

Speaking to Summa Inferno, Chancellor explained that after Tool – whose last album arrived in 2019 – wrap up a run of March shows in Argentina, Chile, Colombia, and Brazil, they plan to “dedicate the next three months after that in the studio to organizing our ideas”.

“There are a lot of stages in the process,” Chancellor continued. “We all have ideas. When they’re good, when we like them, we kind of save them or memorize them. The really difficult process is when you actually get together and make decisions about how it’s going to end up. And that becomes a little more mathematical, a little more like in the classroom — there’s a blackboard and there’s numbers and you have to make decisions. So that’s the stage we haven’t completely pulled off yet, but we’re committed to do that when we get back.”

Noting that the band “have a really good pile of stuff” after its members shared their individual ideas with others, Chancellor noted that the next stage of the process is where things become a lot more complicated.

“You have to make those decisions, and you have to kind of wrestle with each other a bit to get to that next stage,” he explained. “And then you have to record it, which is a whole other thing as well. It’s like a pregnancy, almost. When you go to the studio, you have to make this final decision of how it’s going to sound and how you’re going to play it, and it’s going to live like that forever.”

Though Tool celebrate their 35th anniversary in 2025, their lengthy history has only brought with it a comparatively-meager five full-length records. Famously, a 13-year gap followed the release of 2006’s 10,000 Days, with fifth album Fear Inoculum giving the band their third consecutive Billboard 200 chart-topper upon its August 2019 release.

While the band were forced to contend with a long-running lawsuit that delayed the production of their most recent record, Chancellor – who joined Tool ahead of 1996’s Ænima – defended the length of time the band spends working on material.

“It’s a real delicate thing to be able to pull off,” Chancellor explained. “I don’t think it’s unreasonable that we take a long time at all. I think that’s only natural, and that’s why I’m proud of it, because it was worked on really hard.”

Tool’s Fear Inoculum record also scored the band a pair of Grammy nominations, including Best Rock Song for its title track, and Best Metal Performance for “7empest” – with the band winning the latter. 

Notably, upon the release of 10-minute-and-21-second lead single “Fear Inoculum”, it became the longest song to enter the Hot 100 – dethroning David Bowie’s 2015 single “Blackstar” by 24 seconds in the process.

Tool were themselves outshone by André 3000 by almost two minutes in 2023, when his New Blue Sun album opener “I Swear, I Really Wanted to Make a ‘Rap’ Album but This Is Literally the Way the Wind Blew Me This Time” entered the chart at No. 90.
