Not total, as the newer (last ten years or so) DIJ) is mostly "modern folk" or whatever you call it. But only mostly, Take Care and Control being a good example of something you really cannot categorize under one (or a dozen) genre. And a ballcrushingly great album.
I can put a few songs available at some time if you're interested, though ever that ain't enought to give a good picture, as they've been around since the beginning of the 80's. Heck, you could get a wrong idea about Take Care and Control -album alone even if you'd hear half of the songs from it.
