Jane's Addiction welcomed a pair of guests to the stage during the group's set at the Lollapalooza Festival, first bringing out Rage Against the Machine guitarist Tom Morello to join them on a rendition of Nothing's Shocking's "Mountain Song."
Morello has long been a fan of Jane's Addiction, often crediting the band for inspiring him to stay in Los Angeles and pursue music after his first group Lock Up disbanded. Morello spoke about his Jane's Addiction love when he inducted the group into Guitar Center Hollywood's Rock Walk in 2011.
"[Jane's Addiction] blew my mind and jolted the axis of my understanding of rock music," Morello said at the time. "Nirvana often gets credit for being the first 'alternative' band to break through, the band that changed music and led rock out of the hair metal wilderness of the 1980s. That's just not true," Morello said. "It was Jane's Addiction: inspiring, intelligent, furiously rocking and artistically deep as fuck. As their number one fan, I'm happy to report that my good friends Jane's Addiction are just as great today as that day I snuck into their rehearsal space long ago."
Throughout the years, Morello has popped up onstage with Jane's Addiction to perform "Mountain Song," including a 2009 Connecticut concert and an all-star rendition with Morello, Slash and Travis Barker alongside Jane's Addiction at a 2009 benefit concert in Los Angeles.
Also during Jane's Addiction's set, for their final song at Lollapalooza, the band brought out Smashing Pumpkins drummer Jimmy Chamberlin to add a layer of percussion to "Jane Says."
