The lead single "Black Summer" features Frusciante’s signature watery, sliding guitar tone and a Scottish-tinged vocal from Kiedis. While the album lacks a definitive hit, tracks like "Aquatic Mouth Dance" (featuring horns) and "The Heavy Wing" (where Frusciante takes lead vocals) are pure fan service. It debuted at No. 1—their first chart-topper since Stadium Arcadium . Key Track: "Tippa My Tongue," "Eddie"

This is the “lost” album. With Jane’s Addiction guitarist Dave Navarro replacing Frusciante, the Peppers shifted toward a darker, psychedelic metal sound. One Hot Minute is heavier, more melancholic, and lyrically obsessed with death—Kiedis had relapsed into drug use.

"Dani California" became a global hit, and "Snow (Hey Oh)" is a fingerpicking masterpiece. The album won five Grammys, including Best Rock Album. But behind the scenes, Frusciante was exhausted. He had poured every musical idea he had into the project. After the tour, he left amicably in 2009 to pursue electronic music. Guitarist Josh Klinghoffer, a longtime collaborator, took his place.
