Also idiot kid, Guy Clark and Townes Van Zandt are amazing... You probably know it already, but there's this documentary thing called 'Heartworn Highways' I saw a while ago which has a bunch of live footage of Guy, Townes, Steve Young, John Hiatt, Steve Earle, and a load more of those guys, so yeah, watch that if you haven't already! The soundtrack album is pretty great too.
i have not seen this! those guys all rule though.
oh as far as irish music check out Silly Wizard if you haven't already
oh btw washcycle appalachian folk can be very awesome! i have heard a lot of it but many of the recordings are SOME GUY ON HIS FRONT PORCH so i do not know any names to recommend or anything. if you could that would be dope.
