Guitarist John Frusciante is best known for wailing on Red Hot Chili Peppers songs like 'Give It Away' and 'Californication' during his 10+ year tenure with the band. But the rocker - who turns 47 today - has also collaborated with numerous other artists before, during and since his time with the iconic California band.

Here's the very best of John Frusciante's work without the Red Hot Chili Peppers.

1. Johnny Cash

John Frusciante teamed up with Johnny Cash to record a cover of Depeche Mode's 'Personal Jesus' for the fourth instalment of the country legend's 'American Recordings'. But 'cover' is really an understatement. Frusciante and Cash reinvented the song by stripping away its pop music polish and turning it into a rugged western track.

2. Ziggy Marley

Frusciante gave reggae a whirl in 2003 by teaming up with Ziggy Marley to record 'Rainbow in the Sky' for the album Dragonfly.

3. Johnny Cash Redux

Two months after Johnny Cash's death on Sept. 12, 2003, his estate released the posthumous album 'Unearthed' -- a collection of outtakes and alternate versions of tracks recorded for Cash's 'American Recordings'. The Red Hot Chili Peppers were one of many contributors to the album, with Frusciante lending his axe to Cash's cover of Neil Young's 'Heart of Gold'.

4. The Mars Volta

From 2002-2008, Frusciante moonlighted as a guitarist for the experimental rock group The Mars Volta. He played on tour with the band and in the studio, where he shredded his fingers on the solos on 'L'Via L'Viaquez' from the 2005 album 'Frances the Mute'.

5. Wu-Tang Clan

In 2007, John Frusciante became an honorary member of the rap collective Wu-Tang Clan when he played guitar on 'The Heart Gently Weeps' for the album 8 Diagrams. The track also featured vocals from Erykah Badu and acoustic guitar by Dhani Harrison, which was fitting since the track sampled heavily from The Beatles' While My Guitar Gently Weeps - written by Dhani's father George Harrison.
