Tool kicked off their 2016 US tour at San Francisco’s Bill Graham Civic Auditorium this week. At both dates so far, they’ve opened with their cover of Led Zeppelin’s “No Quarter,” which they also opened with at their Halloween show in Arizona last year, and the setlists have hewed pretty closely to that one. On Thursday night, however, they varied things up a bit by playing “Sweat” from 1992’s Opiate EP live for the first time since 1998. Watch below.
