John Frusciante

His greatest album was made as a solo artist, I think recording it with a 4-track tape and a few kilos of black heroin in his veins ["Niandra LaDes," beautiful and disturbed, also one of my favorite albums of the '90s]...the second one loses almost all the poetry and just remains the delirium of someone with too many drugs and psychotropic drugs circulating. Then, SHIT, both with the RHCP and solo. At least for my tastes, you know..
