On Monday (April 27), Australian EDM duo Knife Party appeared as one of the headliners at this year’s Kingsday Festival in Amsterdam. During their set, they played an unreleased track called “ID,” for which they were joined by none other than Rage Against the Machine guitarist Tom Morello. Check out a fan-shot clip of the performance above. You can listen to another recording of Knife Party and Morello’s collaboration in the Soundcloud player below, too:

Morello’s work with Knife Party is one of a few collaborations the guitarist has recently unveiled. Back in February, Wu-Tang Clan rapper GZA dropped the non-album track, “The Mexican,” which also featured Morello on guitar. They then debuted the song on The Tonight Show Starring Jimmy Fallon the next month.

Morello also recently joined his Rage Against the Machine bandmate Brad Wilk, along with his outfit the Last Internationale, for a rendition of “1968” from the band’s debut effort, last year’s We Will Reign.

Earlier this month, it was also revealed that Morello was working with EDM DJ Skrillex and rapper Jahlil Beats. The latter posted a picture of the three artists on Instagram, writing that they were “working on something epic.”
