Which songs/albums can you recommend? I have travled there first albums and found many pearls,.. but do you have any recommendations?

Californication
Blood Sugar Sex Magik

I think if you really look at the Chili Pepper's music, you see two phases: everything up to Blood Sugar Sex Magik, and everything after One Hot Minute.

Blood Sugar Sex Magik was the culmination of the punk-funk-sex-rock era, and I think Stadium Arcadium is the highest point reached in the...shit, I dunno what you'd call it. To me it sounds ahead of its time, like pop-rock from ten years from now.

Stadium arcadium is the most boring album to me.

Under the Bridge is a good one... Aeroplane is their best old-school song, before they went all gay.

As far as I can tell, Red Hot Chili Peppers and their fans like it in the Other Side (c wat I did that?)
