Anthony Kiedis SPIN interview

After two years off, the Red Hot Chili Peppers are hard at work on their 10th album, due later this year, and, according to frontman Anthony Kiedis, the time apart has reinvigorated the band.

"I think that during the writing of this record I have been the most open-minded and refreshed than I have been in a long time," Kiedis tells SPIN. "I guess that comes from a much-needed hiatus and becoming a father."

While Kiedis was family focused, bassist Flea studied music theory at USC, drummer Chad Smith played with Chickenfoot, among others, and, most stunningly, guitarist John Frusciante quit the band in 2008.

"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."

Flea's musical studies, which included him learning the piano, have helped fill the void left by Frusciante, arming the Peppers with "a whole new dynamic," Kiedis says. And Josh Klinghoffer, who'd previously toured with RHCP as a backing musician, officially became the group's guitarist last year.

"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."

While Kiedis won't reveal song details, he agreed to let SPIN in on the album's affectionate working title, inspired by a friend who dropped by the studio: Dr. Johnny Skinz's Disproportionately Rambunctious Polar Express Machine-head.

"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."
