Song recommendations for learning?

Hi, I'd really like to get more acquainted with Japanese speach and pronounciation, but I can't seem to be able to wade through all the pop content. I'm really not into j-pop, anime openings and soundtracks and that sort of thing. In English I like Hozier, Florence and The Machine, Arctic Monkeys and Celtic. I'm not looking for those exact counterparts of course, but do you have any recommendations for that sort of vibe/feel? You know, something maybe folk-inspired, something a bit more ethereal, or some solid rock?
Thanks in advance
