Exactly two things have remained constant about the Red Hot Chili Peppers over their long and successful career: Flea and Anthony Kiedis. The childhood friends have stayed together as their group's sound and lineup have evolved dramatically over the past three decades.

By our count, the former sock-wearing funk-rockers have gone through eight guitarists, four drummers and 11 lineup changes as they grew into one of the world's most popular rock bands and expanded their sound to include more melodic pop, rock and soul influences. Their history is also marked by numerous members' battles with drug addiction, most tragically resulting in the 1988 death of founding guitarist Hillel Slovak.

Happily, the band seems to have put this drama behind them, with only one lineup change in the last 18 years and their much anticipated 11th studio album, The Getaway, currently receiving favorable reviews and strong early sales.

You can check out each and every one of the Red Hot Chili Peppers' numerous lineup changes above, including the times they counted (sometimes very briefly) members of Parliament-Funkadelic, Jane's Addiction, Black Flag and Danzig among their ranks.
