Tool and Primus closed down their joint tour at the Smoothie King Center in New Orleans last night and during Primus’ opening set, the band welcomed out Tool drummer Danny Carey and current bassist Justin Chancellor for a finale jam on “Southbound Pachyderm.”

Danny Carey filled in with Primus back in 2014 when drummer Tim Alexander suffered a heart attack and underwent successful heart surgery shortly thereafter.

Tool then took the stage for a headlining set that included takes on Led Zeppelin’s “No Quarter” along with a variety of their live staples. Watch a clip of the collaboration below.
