Some rock band that was popular in the early nineties which gave us Dave Navarro. The two other members like Eric Avery and Perry Farrell came from another band called Psi-Com. Jane’s Addiction sold albums fairly well and begat groups like Pornos for Pyros as well as a few comeback albums.
Perry Farrell has branched out working with every other group and even a few solo stints as well as reliving the band’s prime in concerts. I don’t know what the other three are up to but if they’ve moved onto other things, power to them and so be it. But there’ll always be room for people who want to revisit the band’s glory days.
