The bassist played with the British singer in supergroup Atoms for Peace ' which also included punk singer Patti Smith and Gorillaz frontman Damon Albarn ' and said it really helped broaden his musical horizon. He said: "It influenced me being around Thom. He's an unbelievably great musician and a beautiful man. He's so pure as an artist. It's less that I would try to copy him and more that just being around someone who channels really powerful energy is beneficial. "It's a relationship I will always hope to nurture."
While he enjoyed playing with the group during the Red Hot Chili Peppers' two-year break after last album 'Stadium Arcadium', he is glad to get back to his "home" with his other bandmates. He added: "But the Chili Peppers are a different entity. It was inspirational to play with Thom, Damon and Patti but being in a band with Chad [Smith], Anthony [Keidis] and Josh [Klinghoffer] is my home. It's a beautiful thing."
Flea and Josh also took tips from Damon, getting involved with his Africa Express project, which involved an emotional trip for the pair to Ethiopia. Josh explained: "It was like a musical field trip. We had outings every day. It was like summer camp - and then Flea got lost and when he was lost, he went through a lot of emotions which is reflected on the album. It's the point where we were starting to really come together."
