Tom Morello has had a busy year between starting up Prophets of Rage and making guest appearances onstage with various acts throughout 2016. On Aug. 25, the guitarist joined legendary rock artist Bruce Springsteen, performing three songs at The Boss' record-breaking concert.

The MetLife stadium show in N.J. saw Springsteen break his own record for his longest U.S. show, which he had set just two days prior in the same stadium. Performing 33 songs over the course of four hours on the dot, The Boss invited Morello to play "Death to My Hometown," "American Skin (41 Shots)" and "The Ghost of Tom Joad" (video above).

Morello and Springsteen's relationship dates back to 2008 when the Rage Against the Machine guitarist made a pair of guest appearances with the E Street Band. More on and off appearances ensued over the years (including a stint as a touring member of the group in 2013) and Morello played on two songs off Springsteen's 2012 record, Wrecking Balland eight songs off 2014's High Hopes. Morello even traded lines with The Boss on a re-recording of "The Ghost of Tom Joad," much like in the MetLife rendition. Rage Against the Machine also covered the track on their Renegades album.

Prophets of Rage, Morello's new full time outfit with his Rage Against the Machine bandmates Tim Commerford and Brad Wilk along with Public Enemy's Chuck D. and DJ Lord as well as Cypress Hill's B-Real. Their debut EP, The Party's Over was released yesterday (Aug. 26). Catch the group on tour now through Oct. 16 with a list of remaining tour dates here.
