Earlier this week, Tom Morello joined Jane's Addiction on stage in Cologne as part of their UK and European tour.
The Rage Against The Machine lead singer was brought on to the stage, joining the band for a live performance of tracks 'Mountain Song', and 'Chip Away'.
Having performed 'Mountain Song' earlier, Morello made one more guest appearance to round off the show to perform 'Chip Away' with Jane's Addiction.
You can check out both performances for yourselves below.
Tonight, Jane's Addiction will head over to Dublin to performance a headline show at the Trinity Summer Series at Trinity College.
Back in April, Tom Morello also joined Bruce Springsteen on stage at the Kia Forum in California as part of the Boss' world tour.
The pair performed tracks American Skin (41 shots), and The Ghost Of Tom Joad.
This also marked the first time that Springsteen performed American Skin (41 Shots) since 2017, and the first time he performed The Ghost of Tom Joad since 2016.
