Red Hot Chili Peppers acid trip inspired LP working title.

'Dr. Johnny Skinz's Disproportionately Rambunctious Polar Express Machine-head' is the working title of Red Hot Chili Peppers upcoming tenth album, Anthony Kiedis told SPIN.

The ridiculous name was the creation of one of the band's friends, who dropped into the studio with a tale to tell.

"He was reminiscing about one of his legendary acid trips, and told us that he had been playing a sold-out show to the planets and moons, and his number-one hit was, well, that title," Kiedis explains. "We found it so funny that we told him for as long as the album was under the radar, that that would be our nickname for it."

The album, due out later this year, sees a changed band working in a new direction. Kiedis is refreshed after a hiatus and some much needed family time, having recently become a father. Flea, the band's extroverted bassist, has expanded himself studying music theory and piano at USC, while drummer Chad Smith has been playing in the rock supergroup Chickenfoot.

Perhaps the biggest change of all was the departure of prodigious guitarist John Frusciante, and the introduction of guitar slinger Josh Klinghoffer.

"It is always going to change the chemistry and feeling of the music when such a creative force as John Frusciante leaves," Kiedis says. "He was something unique that shaped our sound then, but now I think it's also something fresh and exciting to have a new, incredible musical mind working with us now. We are still the Red Hot Chili Peppers, but we also have to adapt and welcome new opportunities. After all, that is how we've survived all these years."

"This album has been one of evolution," he adds. "Before, some of our jams were a bit hit-and-miss. On this record, a decent number of songs were actually thought out and planned in a way we had never done before. That is, with Flea's new knowledge of music theory, we explored the writing process with a bit more precision."
