Lead singer Chino Moreno (on Maynard's appearance): "Having Maynard perform on the record wasn't something that we planned on doing. We didn't plan on having any guest on the record. But being a fan of Tool and A Perfect Circle, once Maynard was involved, it was just a magical thing for us. Honestly, when he first started working with us, he wasn't supposed to sing with us. He was just working on the arrangements, riff structures, time signatures, and things like that. I don't know if you're a big fan of Tool's music, but they're really mathematical. I've been to their rehearsal space, and there's this big chart that just looks like calculus--the way they write songs, it's just crazy. It was good to have someone else who has different ways of writing songs, 'cause everyone has a different way of doing it. He came in and we started working on this one song in particular, and he just grabbed the microphone and started singing along to it, and my jaw just dropped. All of a sudden our band sounded like Tool; it was just crazy. Then, probably two months later, we went in to record the album, and I went in to record the vocals on it, and I just kept hearing his voice, this re-occurring melody with his voice coming over it. So I called him and asked him if he wanted to come down and sing on the record, and he had no problem with it. Once he came in, I gave him sort of what I wanted the song to be about, and he wrote a couple of ideas down, and the next day he came in with all the lyrics written all out with blank spaces where my lyrics were supposed to be. He's very professional like that. He wants everything set perfectly, which is the complete opposite to the way that I write, so it was cool. And then I went in and did my vocals over it, and it just seemed that our voices blended together pretty good. Yeah, it came out pretty good, so we decided to put it on the record."

Fear Inoculum is the fifth studio album by the American rock band Tool. It was released on August 30, 2019, through Tool Dissectional, Volcano Entertainment, and RCA Records. It is the band's first album in 13 years, due to creative, personal, and legal issues band members encountered since the release of 10,000 Days. It was released to critical acclaim, with reviewers generally agreeing that the band had successfully refined their established sound. The album topped the US Billboard 200 chart, their third in a row to do so, selling over 270,000 album-equivalent units. The album topped five other national album charts in its opening week as well. Two songs off the album received Grammy nominations, the first single "Fear Inoculum", for the Grammy Award for Best Rock Song, and "7empest", for the Grammy Award for Best Metal Performance, with the latter winning the award.
