What if a successful artist like Jimi Hendrix played quietly in his own solitude?

What if an artist like Jimi Hendrix, Jim Morrison, or Elvis Presley never got discovered? What if they just sharpened their talents and worked on their love for music, but stayed in the solitude of their own confinement? Would there actually be a place in the music world for them today? Could they have fathomed a hint of their success before it ever came to them? (Could I have?)
