Fear Inoculum is the fifth studio album by 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 thirteen years, due to creative, personal, and legal issues band members encountered since the release of 10,000 Days. The album 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 albums chart, their third album 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..
