Red Hot Chili Peppers want to play like a "wildebeest let out of a cage that hasn't eaten in six months" live.
'The Adventures of Rain Dance Maggie' group are currently on their I'm With You Tour in Europe and play the O2 in Dublin on Friday night, as well as announcing a gig in Croke Park on June 26 next.
"We're going to do our best to play our hearts out, to let go of our brains and be animals, let the music flow and give every fibre of our being to the process," bassist Flea said.
"I just wanna explode… like a wildebeest let out of a cage that hasn't eaten in six months."
Flea has also recently collaborated with Radiohead's Thom Yorke and former Blur singer Damon Albarn and said he feels "fortunate" to be able to collaborate with such high profile musicians, especially when stars are more segregated than in previous eras.
The musician played with Albarn at the Cork Jazz Festival over the weekend under the name Another Honest Jon's Chop Up.
He added to The Sun: "I love the sense of community in music with different people. I've been really fortunate through all of my life as a musician to play with great musicians.
"It's like in the Sixties, all musicians played with each other, it was like, 'Let's do it'. Now everyone's kind of segregated in to their little businesses - this is our thing, and we're cool, and we have these haircuts over here, so we don't play over there, whatever, we play this style of music.
"It's all bull***t man. Get out and play some music with human beings, who cares about styles or anything - it's music."
Red Hot Chili Peppers will play the O2 in Dublin Friday before their tour moves to the UK next week, then Germany, Austria, Italy, Switzerland and Spain.
The band will then return in 2012 to play Croke Park on June 26 after Knebworth Park, Stevenage, on June 23 and the Stadium of Light, Sunderland, on June 24. Tickets for these shows go on sale on Friday.
