Passage: Frusciante continued to collaborate with his friend Omar Rodriguez-Lopez. Along with providing guitar work to The Mars Volta's studio albums, The Bedlam In Goliath and Octahedron, and Rodriguez-Lopez's solo albums Se Dice Bisonte, No Bufalo and Calibration (Is Pushing Luck and Key Too Far), he functioned as executive producer for Rodriguez-Lopez's directorial film debut, The Sentimental Engine Slayer.

The first is the album Omar Rodriguez-Lopez & John Frusciante, an album with just the two of them, the other a quartet record, Sepulcros de Miel, consisting of Rodriguez-Lopez, Frusciante, Juan Alderete and Marcel Rodriguez-Lopez.
Frusciante also contributed music to the documentary film, Little Joe, based upon Joe Dallesandro. In 2009, Frusciante appeared in the documentary, "The Heart is a Drum Machine." His full-length, forty-five-minute interview is available in the special features of the DVD release.On December 7, 2011, the Red Hot Chili Peppers were named 2012 inductees for the Rock And Roll Hall Of Fame. In an interview that same day, Anthony Kiedis talked about Frusciante and if he would attend the ceremony. Kiedis stated, "It would be a guess on my behalf on whether or not he'll come. I can't imagine that he would, but it's a 'you never know' kind of thing. I haven't talked to him in quite a while. I don't know where he's at these days. He'll obviously be more than welcome, and embraced if he does. If he doesn't, that's cool too." Flea also spoke about Frusciante by saying "He left us so many great gifts. He's a phenomenal musician and songwriter who gave so much to our band. All the feelings I have for him not being in the band any more ... He really took us to a higher level." Frusciante eventually declined to be present for the Red Hot Chili Peppers' induction into the Rock and Roll Hall of Fame in April.
