The full original lineup of Jane's Addiction may be reunited, but members of the volatile quartet are already at each other's throats, just like in the old days. According to Reuters, the group has been fighting nonstop since they got back together for the first time since 1991 to record new songs with their producer and tour mate, Nine Inch Nails' Trent Reznor. Apparently things got so heated in the studio that Reznor was forced to act as a mediator in the ongoing battles between singer Perry Farrell and bassist Eric Avery, the only member of the band to not participate in previous Jane's Addiction reunions. Truly, if Trent Reznor is the guy doing your intervention, you know you've got some serious problems. Despite the incessant feuding, Farrell remains inexplicably optimistic, chalking up the band's severe interpersonal dysfunctions to quasi-hippie stuff like "vibrations." When asked about his troubles with Avery, Ferrell explained, "We're different people, that's okay. He serves a different purpose, he's got a different frequency he operates on. I'm overjoyed that we're working together. I don't care that we butt heads as long as when we hit the stage we blast on people." Good luck with that, Perry!
