This album is a lot more experimental than Californication and doesn't have as many catchy pop vocals yet it is still an awsome cd.
After a few listens you will see the beauty in every song.

To be honest, I don't really care for the album. It's too slow and mellow for these guys. I liked 3 songs on the album - out of 16. If you're a hardcore RHCP fan, you'll enjoy it though. Listen to it before you buy it.
