What an utterly bizarre selection. No Love Over Gold, Making Movies or Shangri-La, but Ragpicker’s Dream and Tracker make it?!
It's about Americana style music, so for sure I don't see Love Over Gold there, and also Making Movies I would say.
In any case, any list made by one person is... personal, but I found it interesting precisely because Mark is not an artist who is 'categorised' in the Americana genre, but lovers of the genre can find a lot in his music. The same goes for those who love rock, blues, folk, I think. That's one of the great merits of Mark, and especially of 'solo' Mark, in my opinion.
