Apart from an early dalliance with Joe Ely thanks to the Clash way back when, I really started with the Byrds, onto Gram Parsons, noting his influence on the Stones on the way and became utterly infatuated with Emmylou thanks to her contribution to the 2 solo albums and Wrecking Ball. After that it was a downward spiral with Lyle Lovett, Steve Earle, the man in black of course, Lucinda Williams, Ryan Adams and a host of others. Mostly biased towards the rockier end of the spectum.
Try Joshua Judges Ruth by Lyle Lovett if you haven’t already. Love Williams’s Essence & World Without Tears. Latter is in my all time top-ten
