In a conversation with Rolling Stone, Jane's Addiction frontman Perry Farrell teased an upcoming project that he says he hopes will be his "shining and greatest achievement in life." All he revealed is that it's a non-Jane's Addiction endeavor, although the band will "test-pilot" it, and that it will exist on multiple forms, some that transcend media.

Farrell said, "We will be breaking ground. It's very music-centric, but it is inclusive of technology, film, theater and even the gastronomic arts. It's going to be the greatest thing I've ever done."

Assuming all goes as he hopes, whatever he's working on wouldn't be Farrell's first major success outside of Jane's Addiction, as he is also the founder of the Lollapalooza festival. He also talked about how he is "honored" to have Metallica headlining this year's festival, although he wasn't always too keen on them.

"[Metallica were] not the first group that I didn't want to play Lollapalooza, because I have an obligation to my patrons," Farrell said. "I'm all about genuine, authentic, heartfelt, the real deal. So I was not sure about Metallica back in those days. It's my f---ing party and I'll have who I want." He added that, now, "I like their music."
