The return of John Frusciante is certainly a boon to the group and likely resulted in the more mature sound found on this record. That seems like a bit of an oxymoron for the Chil Peppers, but we'll get to that in a minute. Frusciante's influence, and the weight of his recovery from addiction, seems to have tempered the chemistry of the group. Not only does he bring his earworm guitar lines, but there is also an increased use of backing vocals that brings some more sophistication and beauty to the material. Flea is one of the few truly iconic bass players in modern rock since the late 80s. He is certainly flamboyant, but never seems to overplay. It's just that he has the ability to play so much more than your average bassist, and he uses that ability to support the songs. His relationship with his partner in rhythm, Chad Smith, is obviously essential to their success. He, like many drummers, seems to be the silent glue that holds everything together. Then we get to Anthony Kiedis and this is where it gets more complicated. His voice is an integral part of the Chili Pepper's sound and I do appreciate his soulfulness and even playfulness. But it's the lyrics that get to me sometimes. There are some nice poetic moments here and there but there are also these groan worthy awkward phrases throughout that prevent it from being truly great. It's like he never grew out of being a teenager and his cringeworthy thoughts are on full display. I know they sort of embrace that to a certain degree but it still doesn't make it go down easier or age more gracefully. This is a 3.5 for me and I will round up to 4 since I did enjoy this more upon it's initial release and I remember the vast majority of these catchy songs quite well and relatively fondly. However it just as easily could have been a 3 just for the lyrics.
