Been caught sparring: A concert by the reunited Jane’s Addiction in Boston came to a sudden end Friday night when a clearly enraged Perry Farrell threw a punch guitarist Dave Navarro — and was restrained by crew members, still appearing physically agitated as he was hustled offstage.

Multiple audience members shared their dramatic video of the altercation from different vantage points in the crowd after the gig ended in calamity. The footage shows the band deep into playing “Ocean Size,” the 11th number in a set that usually stretches out to 14 or 15 songs, when trouble erupts between the two most famous members of the veteran band.

Social media posts from fans revealed that tensions between band members were escalating over several songs before the physical altercation. Footage of the incident shows Farrell growling intensely at the audience, then turning toward Navarro and shouting. He appears to forcefully push Navarro, who stops playing and raises a hand to create space between them. Farrell then allegedly punches Navarro in the chest. Three individuals, including bassist Eric Avery, can be seen shouting, "stop" and surrounding Farrell. He is eventually escorted off stage by the trio, continuing to struggle as he's ushered backstage.

After Farrell departs the stage, the rest of the band, including Navarro, steps forward to acknowledge the crowd, appearing calm as they embrace each other, applaud, touch their hearts, and offer a peace sign.

The altercation immediately went viral on social media, with a deluge of jokes — including countless Oasis comparisons — alongside more serious concerns expressed for the well-being of the band members involved.

“I was there,” @deanasc1 tweeted on X. “The crowd was a mix of confusion and excitement. Some were upset the show ended early, while others thought it might be the last Jane's Addiction performance.”

“Jane’s Addiction broke up before Oasis omg,” was a typical tweet, from the user @Tribecalledflex .

On setlist.fm , the notes section for the Boston show provides a quirky detail: “Note: Stephen Perkins’ drum set was decorated with balloons for his birthday. The show ended prematurely after Perry Farrell physically confronted Dave Navarro .”

Representatives from Jane’s Addiction and the concert organizer, Live Nation, were unavailable for comment Friday night.

Rumors had already been circulating on social media about the Jane's Addiction shows earlier this week in New York City, held at the Rooftop at Pier 51. At the first of two concerts there, Farrell confessed to the audience that his voice was not in optimal condition, reportedly stating, “Ladies and gentlemen, I have to be honest with you. Something's wrong with my voice. I just can’t hit the notes all of a sudden.” The following day, bandmate Eric Avery posted on Instagram, “Looking forward to another shot at this amazing rooftop venue tonight. I’m optimistic we will be better.”

The following night in New York, the situation took a positive turn, according to a reviewer for JamBase who wrote, “Having read reports of Farrell's behavior on Tuesday, I was apprehensive as Jane's Addiction took the stage. My worries quickly subsided, as my first Jane's experience was fantastic. Farrell sang well, Perkins excelled on drums, Navarro delivered impressive guitar work, and Avery provided a solid foundation with his bass playing.  … Some of (Farrell's) stories were captivating, while others meandered as he sipped wine. He also focused on a device that seemed intended to add effects to his vocals, but had minimal impact to my ears. However, when it came to singing the songs, Farrell nailed most of them.”

Ironically, considering subsequent events, the singer intervened to stop a fight at the band's second New York show. “Farrell actually halted the song after noticing a dispute among audience members,” JamBase reported. “Farrell made a fan named ‘Bobby’ reconcile with the person he was arguing with.”

A review of the band's Tampa show earlier this month in Creative Loafing might provide insight into the source of tension between Farrell and Navarro. The Florida critic reported: “Farrell engaged in nonsensical rambling about various topics, including cow pastures, mushrooms, surfing, life in Florida, and political arguments with his brother … During one of his tangents, Navarro intentionally played a loud, piercing chord on his guitar, seemingly to silence Farrell and bring the performance back on track.”

Jane's Addiction's first tour in 15 years is a co-headlining event, featuring another popular 90s band, Love & Rockets, as the other act.

The unfortunate Boston incident occurred on Friday night, approximately 20 shows into the bands' joint tour. With 15 performances remaining, the tour is currently scheduled to continue and conclude on October 16 at L.A.'s YouTube Theater, returning to the same venue where the group successfully performed in mid-August.
