It's reassuring to realize just how little the Chilis have changed in the five years since their last album—or in the two decades since Blood Sugar Sex Magik, for that matter. So what if guitarist John Frusciante quit (again) during their most recent hiatus? The remaining members seem to be the same lovable goofballs as always. Their big comeback single, from August 30th's I'm With You, has everything you want from the Chilis: Flea and Chad Smith cook up a juicy funk-pop groove with plenty of cowbell, new guitarist Josh Klinghoffer kicks in some rangy riffs, and Anthony Kiedis woos a wild child with the type of come-ons only he can deliver with a straight face ("Ticktock, I want to rock you like the Eighties") before leaning into a huge, pleading hook. Welcome back, dudes.
