Terry Kath is a good comparison to Hendrix as both so much talent and more potential, I like many of my generation were close in age to the artist that emerged during the 60s and since. ,it is looking at a black and white snapshot from a time long removed from the present. And the artist that died young are frozen in time. Cut down and therefore locked into that level of artistry they had reached.
Think of Prince, had he joined the 27 club, (died at age 27) look what we would have missed. And he would have been one of those black and white snapshots forever frozen in time.
Hank Garland, perfect example, he was on top of the world, no question one of the hottest players, in demand by all the biggest stars of the time a car accident leaves him crippled with a severe brain injury. He lives in obscurity and fades away. Had it not been for that crash, the sky was the limit,.
It's just the way it is, guys like Hendrix are so much more rare , not because they played well, it was an entire package, The Experience. He changed the way other artist approached music. Technically he still had room for growth, that was part of the intrigue of Jimi, we all knew he was going to blow our mind with his next release.
Till he couldn't, so now he is the bell bottom wearing whah whah guy with stacks of Marshall amp and flaming strats
Showmanship was his power, sadly his snapshot will always be what is in the four records he released.
Same with Kath. Garland, Morrison, and others
