Probably so, it so happens that not all human beings have all that clarity from the start, some have to learn it through time. Cash was a great artist, and was like that for years. True, at the beginning he was just another "pop" artist like Elvis or whatever, but the thing is he changed for good, and I don't think it was only death impending, though that's just my point of view. It is also true that Cale was like that from the start, maybe because he was used to be out of the limelight, to put it somehow. He said he liked it being the engineer or the side musician, until he got used to be in the center of attention. Cash had a complex life, many temptations, on the other hand.
