One of the jazz greats .a lot of them in the 50s 60s 70s were heroin addicts im not advocating using heroin but it somehow enhanced them musically..chet baker,bill evans,miles davis,but coltrane died of a heart attack pretty young..no drugs ..the 50s was a different time..you went to prison..no rehabs..i think peppers album straight life is my favorite..excellent recordings vinyl and cd..have both..nothing like stereo 2 track 15ips reel to reel analog recordings with excellent tube microphones..
