I probably have all of those listed by Audiofeil, and I refer to his list solely because it includes Bob Dylan ... I grew up with Dylan and still, to this day, enjoy hearing his music .... maybe everyone does ... I don't know

In the '60s I bought my first Coltrane albums ... today I still have Coltrane and a lot of others ...

I will second Richard Thomopson. I would also like to add James McMurphy and Steave Earle.
