Where often he discusses other books, music etc.

From what I have read, I think he would like the group 'The Floating Men', who are out of Nashville, and especially their new "album" called No Clocks No Calendars Act 1. The 16 or so songs express a story arc (Lowcountry voodoo amidst the tourists, basically) that seems up his alley.

That's all. Oh yes, I enjoy his books, especially all things Dark Tower-related, keep it up.
