LOS ANGELES — The members of alternative rock band Jane’s Addiction filed dueling lawsuits Wednesday over singer Perry Farrell’s onstage scuffle with guitarist Dave Navarro at a Boston concert last year, prompting the cancellation of the rest of their reunion tour and a planned album.

Navarro, drummer Stephen Perkins and bassist Eric Avery sued Farrell in Los Angeles Superior Court seeking at least $10 million, alleging that Farrell’s behavior on the tour had ranged from erratic to out-of-control, culminating in the assault, where Perry punched Navarro both on stage and backstage.

“With a series of swift blows, he single-handedly destroyed the name, reputation, trademark, and viability of the Band and those who built it,” their lawsuit says.

Farrell and his wife, Etty Lau Farrell, sued the three bandmates in the same court Wednesday, blaming them for the conflict and the violence.

“Navarro, Avery and Perkins apparently decided,” the lawsuit says, “that Jane’s Addiction’s decades of success should be jettisoned in pursuit of a yearslong bullying campaign against Farrell involving harassing him onstage during performances, including, among other tactics, trying to undermine him by playing their instruments at a high volume so that he could not hear himself sing.”

The Farrells said that Navarro and Avery actually assaulted them.

Perry Farrell said he was “blindsided” when the other members canceled the remaining 15 shows of the tour and broke up the band without consulting him, costing all of them a great deal of money.

And he said his bandmates defamed him by publicly saying after the fight that he had mental health problems.
