The band also contributed the John Lennon song "I Found Out" to the Working Class Hero: A Tribute to John Lennon album, as well as the One Hot Minute outtake "Melancholy Mechanics" to the Twister soundtrack.
In 1995, Navarro played guitar for Alanis Morissette's track "You Oughta Know" on one of the 1990s most successful albums, Jagged Little Pill.
Navarro toured with Jane's Addiction for their 1997 Relapse tour with Flea on bass.
The band assembled for the accompanying US tour consisted of Navarro, guitarist Dave Kushner, bassist Miiko Watanabe and drummer Angel Roché, Jr..
In 2002, Jane's Addiction reformed with bass player Chris Chaney, and started work on a new album.
Navarro is best known as a founding member of the alternative rock band Jane's Addiction (four studio albums) and as a former member of the Red Hot Chili Peppers (one album).
He also released one solo album Trust No One (2001).
They certainly don’t seem like political opposites, however, as Navarro performed at the 2012 Republican National Convention.
